Change group ownership of /var/mail to mail and permission

to 0775.

This does *not* instantly make any program which "ensures"
mail spool consistency by creating lock files safe in any way
since other tools, like mail.local, will be using flock() semantics
and any such lock file will simply be ignored.  It does, however,
allow a lot of things which are currently suid root in order to create
such bogus lockfiles to, at least, be bogus at a much lower level of
privilege (and this is good).  Ultimately, of course, everybody should
just use flock.
