run: --no flag is actually a general flag

There is nothing specific to qemu in the --no flag,
but it was on the qemu group. Let's move it to
the general group.

qemu/cfg/tests.cfg - Exclude multi host tests

Multi host tests can't be executed on the standalone
runner, so we've got to filter them out. This way
we'll have a lot less results displayed when listing
tests for, say, Fedora.18.x86_64, but the list will
be more accurate.
