minstall: always track meson-created directories

If a custom_target output is a directory, we install it as a directory,
not as a file. And, we try to track subdirectories which are created so
uninstalling works. But one directory creation did not go through
DirMaker, in the case where the output directory does not have any
further subdirectories.

Consolidate on makedirs, since I don't see much point in using os.mkdir
right here.
