mkosi: Move TEST-24-CRYPTSETUP files to mkosi/ directory

If the integration tests have been installed in the systemd-tests
package, the path to these in mkosi.postinst.chroot will be wrong.
Let's fix the issue by moving these files into the mkosi/ directory
as they're only used by mkosi regardless so they make more sense to
be there anyway.
