This change moves the open coded clean up logic from get_cycle_centroid() into vec_delete() to fix this and make it less likely that this is missed in future. This was initially encountered while investigating #1554.

make_label() internally strdups its input, so this extra allocation was simply being lost. This was observable using an ASan-instrumented build and the command `dot -Tsvg -o /dev/null ./rtest/share/alf.gv`: Direct leak of 121 byte(s) in 12 object(s) allocated from: #0 0x7fd2541bf810 in strdup (/lib/x86_64-linux-gnu/libasan.so.5+0x3a810) ellson#1 0x7fd25404a955 in parse_reclbl /tmp/tmp.bXYbsH93VJ/graphviz/lib/common/shapes.c:3314 ellson#2 0x7fd25404a5eb in parse_reclbl /tmp/tmp.bXYbsH93VJ/graphviz/lib/common/shapes.c:3292 ellson#3 0x7fd25404ca5f in record_init /tmp/tmp.bXYbsH93VJ/graphviz/lib/common/shapes.c:3556 ellson#4 0x7fd25405966a in common_init_node /tmp/tmp.bXYbsH93VJ/graphviz/lib/common/utils.c:658 ellson#5 0x7fd24fc78a01 in dot_init_node /tmp/tmp.bXYbsH93VJ/graphviz/lib/dotgen/dotinit.c:40 ellson#6 0x7fd24fc79522 in dot_init_node_edge /tmp/tmp.bXYbsH93VJ/graphviz/lib/dotgen/dotinit.c:81 ellson#7 0x7fd24fc7ad61 in dotLayout /tmp/tmp.bXYbsH93VJ/graphviz/lib/dotgen/dotinit.c:295 ellson#8 0x7fd24fc7c4b9 in doDot /tmp/tmp.bXYbsH93VJ/graphviz/lib/dotgen/dotinit.c:450 ellson#9 0x7fd24fc7ca94 in dot_layout /tmp/tmp.bXYbsH93VJ/graphviz/lib/dotgen/dotinit.c:496 ellson#10 0x7fd253f7673d in gvLayoutJobs /tmp/tmp.bXYbsH93VJ/graphviz/lib/gvc/gvlayout.c:85 ellson#11 0x55a9961b3960 in main /tmp/tmp.bXYbsH93VJ/graphviz/cmd/dot/dot.c:132 ellson#12 0x7fd253d2309a in __libc_start_main ../csu/libc-start.c:308 Direct leak of 118 byte(s) in 19 object(s) allocated from: #0 0x7fd2541bf810 in strdup (/lib/x86_64-linux-gnu/libasan.so.5+0x3a810) ellson#1 0x7fd25404a955 in parse_reclbl /tmp/tmp.bXYbsH93VJ/graphviz/lib/common/shapes.c:3314 ellson#2 0x7fd25404ca5f in record_init /tmp/tmp.bXYbsH93VJ/graphviz/lib/common/shapes.c:3556 ellson#3 0x7fd25405966a in common_init_node /tmp/tmp.bXYbsH93VJ/graphviz/lib/common/utils.c:658 ellson#4 0x7fd24fc78a01 in dot_init_node /tmp/tmp.bXYbsH93VJ/graphviz/lib/dotgen/dotinit.c:40 ellson#5 0x7fd24fc79522 in dot_init_node_edge /tmp/tmp.bXYbsH93VJ/graphviz/lib/dotgen/dotinit.c:81 ellson#6 0x7fd24fc7ad61 in dotLayout /tmp/tmp.bXYbsH93VJ/graphviz/lib/dotgen/dotinit.c:295 ellson#7 0x7fd24fc7c4b9 in doDot /tmp/tmp.bXYbsH93VJ/graphviz/lib/dotgen/dotinit.c:450 ellson#8 0x7fd24fc7ca94 in dot_layout /tmp/tmp.bXYbsH93VJ/graphviz/lib/dotgen/dotinit.c:496 ellson#9 0x7fd253f7673d in gvLayoutJobs /tmp/tmp.bXYbsH93VJ/graphviz/lib/gvc/gvlayout.c:85 ellson#10 0x55a9961b3960 in main /tmp/tmp.bXYbsH93VJ/graphviz/cmd/dot/dot.c:132 ellson#11 0x7fd253d2309a in __libc_start_main ../csu/libc-start.c:308
