Remove setup_X_sockets():

The creation of Unix sockets directories in /tmp for X happens right
after pruning /tmp. So the whole dance of checking for their
existence, ownership or permissions is not necessary. It's safe to
just create them with the right permissions if X is installed.
Changes to do_fsck():
Remove the _flags variable and pass flags to fsck directly with "$@".
