test/cmdline: fix inputs array

[ upstream commit 414245b ]

clang 12 gives a warning about string concatenation in arrays.
In this case it looks like it was unintentional to concatenate
the strings. Separate with a comma.

$ clang --version
clang version 12.0.0 (Fedora 12.0.0-0.3.rc1.fc34)

../app/test/test_cmdline_ipaddr.c:259:3: warning:
suspicious concatenation of string literals in an array initialization;
did you mean to separate the elements with a comma?
[-Wstring-concatenation]
"random invalid text",
^
../app/test/test_cmdline_ipaddr.c:258:3: note:
place parentheses around the string literal to silence warning
"1234:1234:1234:1234:1234:1234:1234:1234:1234:1234:1234"
