test: Skip qemu tests if skiboot.lid is too large

With the addition of the secvar patches the GCOV enabled builds now
produce a skiboot.lid that greater than 4MB. This is larger than the
historical max firmware image size supported by the PowerNV Qemu model
so we need to skip the Qemu boot tests in that case.

Non-GCOV builds are still well under the limit (2.3MB or so) and mambo
tests are not affected, so this shouldn't be a big deal. If the Qemu
happens to support a larger image size this should continue to work
without issues.
