Stian Ellingsen dc3d6a6db1 Use env, not sh in zfsctl_snapshot_{,un}mount()
Call mount and umount via /usr/bin/env instead of /bin/sh in
zfsctl_snapshot_mount() and zfsctl_snapshot_unmount().

This change fixes a shell code injection flaw.  The call to /bin/sh
passed the mountpoint unescaped, only surrounded by single quotes.  A
mountpoint containing one or more single quotes would cause the command
to fail or potentially execute arbitrary shell code.

This change also provides compatibility with grsecurity patches.
Grsecurity only allows call_usermodehelper() to use helper binaries in
certain paths.  /usr/bin/* is allowed, /bin/* is not.
