Gitlab: Drop vexpress_fvp from tests

Gitlab: Drop vexpress_fvp from tests

Now that we have a test for QEMU using transfer list from the previous
stage, there are two platforms testing this particular infrastructure. A
problem with the vexpress_fvp platform emulation in Gitlab is that we
often run it on hosts that are fast enough that we run in to a race
condition when trying to acquire the console and the test fails. Remove
both vexpress_fvp tests from Gitlab (they can remain in Azure) to remove
these spurious failures.
