mountd exits if it cannot read any exports files. Requiring /etc/exports, however, unconditionally stops mountd from starting on a server that exports ZFS datasets only (/etc/zfs/exports). Let sbin/mountd handle requirements itself, instead of hardcoding /etc/exports, which is also wrong, because different files can be specified in mountd_flags. This patch also works with nfsv4_server_enable="YES", by preserving the behavior of failing to start if there is no "V4:" line in the exports file, which is missing by default on ZFS-only exports.
