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.
