Title: Adds support for selinux's rootcontext mount option

adds a dataset property, ROOTCONTEXT (ZFS_PROP_SELINUX_ROOTCONTEXT),
that can store the rootcontext you wish to have the dataset mounted as
when running on selinux. If no rootcontext is specified it will default
to "system_u:object_r:fs_t".
