Use concise order for 'install' command

Sync change with upstream gtk3:
https://gitlab.archlinux.org/archlinux/packaging/packages/gtk3/-/commit/508eaa789978476622412c7f90c848adb4dcd0df#9b9baac1eb9b72790eef5540a1685306fc43fd6c_127_135

No difference to output. Just the order of commands changes.

-D:    Creates any missing directories.
-m644: Sets file permissions to 644.
-t:    Target directory.
