[PATCH v2 4/5] automation: Add a gzip compressed kernel image test on arm32

[Michal Orzel <michal.orzel@xxxxxxx>]

Xen supports booting gzip compressed kernels, therefore add a new test
job qemu-smoke-dom0less-arm32-gcc-gzip in debug and non-debug variant
that will execute qemu-smoke-dom0less-arm32.sh script to test booting
a domU with a gzip compressed kernel image (in our case zImage).

By passing "gzip" as a test variant, the test will call gzip command
to compress kernel image and use it in ImageBuilder configuration for
domU1. No need for a specific check to be executed from domU. Being able
to see a test message from a boot log is sufficient to mark a test as
passed.

Changes in v2:
 - take into account dom0 presence
 - drop Rb as a result of code changes
