path.c: mark 'logs/HEAD' in 'common_list' as file

'logs/HEAD', i.e. HEAD's reflog, is a file, but its entry in
'common_list' has the 'is_dir' bit set.

Unset that bit to make it consistent with what 'logs/HEAD' is supposed
to be.

This doesn't make a difference in behavior: check_common() is the only
function that looks at the 'is_dir' bit, and that function either
returns 0, or '!exclude', which for 'logs/HEAD' results in 0 as well.
