Try to correct any confusion about QEMU's Byzantine disk options by
laying out the preferred "modern" options as-per:

 "<danpb> (best:  -device + -blockdev,  2nd obsolete syntax: -device +
     -drive,  3rd obsolete syntax: -drive, 4th obsolete syntax: -hdNN)"

test_postcopy() is currently run twice - which is just a waste of resources
and time. The commit d1a27b16 that introduced the duplicate talked about
renaming the "postcopy/unix" test, but apparently it forgot to remove the
old entry. Let's do that now.

When KVM is not available, the i386 migration test also runs in a rather
slow fashion, since the guest code takes a couple of seconds to print
the "B"s on the serial console, and the migration test has to wait for
this each time. Let's increase the frequency here, too, so that the
delays in the migration tests get smaller.

The migration tests spend a lot of time waiting for a sign of live
of the guest on the serial console. The aarch64 migration code only
outputs "B"s every couple of seconds (at least it takes more than 4
seconds between each characeter on my x86 laptop). There are a lot
of migration tests, and if each test that checks for a successful
migration waits for these characters before and after migration, the
wait time sums up to multiple minutes! Let's use a shorter delay to
speed things up.

While we're at it, also remove a superfluous masking with 0xff - we're
reading and storing bytes, so the upper bits of the register do not
matter anyway.

With these changes, the test runs twice as fast on my laptop, decreasing
the total run time from approx. 8 minutes to only 4 minutes!
