We don't install dot.nsmbrc or smbfs.sh.sample, since we already install
the former as /etc/nsmb.conf and the latter is unnecessary, since
boot-time mounts can be arranged directly within /etc/fstab without fear
of breaking the boot when the smbfs port (now unnecessary is removed).
The MFC reminder below is subject to <re@FreeBSD.org> approval
