patch to mount(8): allow specifying options during 'mount -a'

Hi,

This patch allows options to be specified on the command line when
mounting all filesystems.  e.g. mount -a -o sync,nodev

Seems like a good idea from the orthogonality/POLA viewpoint at least.

Thought it would probably be wise to get it in before making other
changes to mount.c.

Backported from The FreeBSD Project.  Lightly tested.
