meson already supports $DESTDIR natively, but in this case
we're using a custom script and so we have to do some extra

I don't see any reason for this check. Yes, DESTDIR is mostly used with
absolute path but the other two scripts where we use DESTDIR don't have
this check and meson itself doesn't complaint if the path is
not absolute as well.
That brings me to the other point that there is no need to use pathlib
at all. We can just do the same as scripts/meson-install-dirs.py or
scripts/meson-install-symlink.py:
destdir = os.environ.get('DESTDIR', os.sep)
for desc in sys.argv[1:]:
inst = desc.split(':')
dst = os.path.join(destdir, inst[1].strip(os.sep))
os.makedirs(dst, exist_ok=True)
shutil.copy(src, dst)
