[dconf] Simplify 'shmdir' checks

[Ryan Lortie <ryanl src gnome org>]

commit 7b99c368158db2f622c1bb01de4bdde62270c2d0
Author: Ryan Lortie <desrt desrt ca>

    Simplify 'shmdir' checks
    
    With XDG_RUNTIME_DIR, we no longer have to be frightened about NFS.
    That lets us remove the NFS checks that were causing build failures all
    over the place.
