scripts: kwbimage: fix build with non-glibc systems
get_current_dir_name is a glibc extension, thus replace it with a call to standard POSIX pathconf/malloc/gecwd. The result slightly differs, because get_current_dir_name consults the $PWD environment variable as as well, but that's ok, as it's just an error message.
