builtin-apply.c: Skip filenames without enough components
find_name() wrongly returned the whole filename for filenames without
enough leading pathname components (e.g., when applying a patch to a
top-level file with -p2).
Include the -p value used in the error message when no filenames can be
found.
[jc: squashed a test from Nanako Shiraishi]
