Thomas Huth ef6c47f1d7 tests/pxe: Use -nodefaults to speed up ppc64/ipv6 pxe test
SLOF is unfortunately quite slow when running with TCG, so
the pxe test is also performing rather slow here. By using
"-nodefaults" we can disable some devices (vscsi) that we
are not interested in here, so that SLOF does not have to
scan them during boot and thus starts up a little bit faster.
The ppc64 pxe-test now only takes 27 seconds on my laptop
instead of 33 seconds.
The "-nodefaults" flag seems to work fine for the x86 tests,
too, so it is added here unconditionally here (though there
is no speed-up on x86 by using this flag).
