Pawel Jakub Dawidek e651144614 Imagine a situation where:
# ls -ld /mnt/{foo,bar}
	drwxr-xr-x  3 root  wheel  512 Mar 16 06:56 /mnt/bar
	lrwxr-xr-x  1 root  wheel    3 Mar 16 12:10 /mnt/foo -> bar

	# grep /mnt/foo /etc/fstab
	/dev/da1	/mnt/foo	ufs	rw	0	0

Which means, we give symbolic link as a mount point to mount(8), but mount(8)
use realpath(3) before mounting the file systems, so we get:

	# mount | grep /dev/da1
	/dev/da1 on /mnt/bar (ufs, local)

Before the commit:

	# snapinfo /mnt/foo
	usage: snapinfo [-v] -a
	       snapinfo [-v] mountpoint
	# snapinfo /mnt/bar
	/mnt/bar/snap

This commit makes snapinfo(8) to first realpath(3) the given mount point and
now we have:

	# snapinfo /mnt/foo
	/mnt/bar/snap
	# snapinfo /mnt/bar
	/mnt/bar/snap
