blame: simplify 'setup_blame_bloom_data' interface

The penultimate commit moved the initialization of 'sb.path' in
'builtin/blame.c::cmd_blame' before the call to
'blame.c::setup_blame_bloom_data'. Since 'cmd_blame' is the only caller
of 'setup_blame_bloom_data', it is now unnecessary for
'setup_blame_bloom_data' to receive 'path' as a separate argument, as
'sb.path' is already initialized.

Remove this argument from setup_blame_bloom_data's interface and use the
'path' field of the 'sb' 'struct blame_scoreboard' instead.
