[PATCH] swapon: add -v, --verbose argument

[Justus Winter]

This patch adds a --verbose argument to swapon and swapoff to make it
more compatible with the corresponding Linux' utilities. Note that our
swapon is verbose by default and has a --quiet argument to make it
quiet, so a --verbose argument on it's own does nothing at all.

* sutils/swapon.c (main): Handle -v argument.
