This is a followup to 884a609a77 ("btrfs-progs: add basename
wrappers for unified semantics"). Test cli/019-subvolume-create-parents
fails as there are paths with trailing slashes.
The GNU semantics does not change the argument of basename(3) but this
is problematic with trailing slashes. This is not uncommon and could
potentially break things.
To minimize impact of the basename behaviour depending on the include of
libgen.h use the single wrapper in path utils that has to include libgen
anyway for dirname. Our code passes writable buffers to basename.
Issue: #778
