siv0 41e55b476b Fix nfs_truncate_shares without /etc/exports.d ... Calling nfs_reset_shares on Linux prints a warning: `failed to lock /etc/exports.d/zfs.exports.lock: No such file or directory` when /etc/exports.d does not exist. The directory gets created, when a filesystem is actually exported through nfs_toggle_share and nfs_init_share. The truncation of /etc/exports.d/zfs.exports happens unconditionally when calling `zfs mount -a` (via zfs_do_mount and share_mount in `cmd/zfs/zfs_main.c`). Fixing the issue only in the Linux part, since the exports file on freebsd is in `/etc/zfs/`, which seems present on 2 FreeBSD systems I have access to (through `/etc/zfs/compatibility.d/`), while a Debian box does not have the directory even if `/usr/sbin/exportfs` is present through the `nfs-kernel-server` package. The code for exports_available is copied from nfs_available above.
