On UFS with SU+J, sometimes fsck's default recovery from journal marks the
filesystem as clean but some errors remain.
With SU only, default fsck in preen mode sometimes thinks all errors have
been fixed but some still remain.
To address the issues above, this change adds a new config option:
fsck_flags. By default it's set to -p, but the user may change it to -y
or -f -y, for instance, to force a full fsck after a system crash.

The reasons for this are forward looking to pkgbase:
* /sbin/init is a special binary; try not to replace it with
every package update because an rc script was touched.
(a follow-up commit will make init its own package)
* having rc in its own place will allow more easy replacement
of the rc framework with alternatives, such as openrc.
