[PATCH 1/4] mount: add -n and --no-mtab arguments

[Justus Winter]

Add -n and --no-mtab arguments. As we do not write an mtab file, this
is a trivial patch that just ignores this argument to be more
compatible with Linux mount.

* utils/mount.c (argp_opts): Add -n and --no-mtab.
(parse_opt): Do nothing on 'n'.
