tests/functional/test_aarch64_rme_virt: fix sporadic failure
This test was randomly failing on our CI, and on dev machines,
especially with QEMU debug builds.
>From the information collected, it's related to an implementation choice
in edk2 QEMU virt support. The workaround is to disable KASLR, to avoid
accessing protected memory.
Note: this is *not* needed for the similar test_aarch64_rme_sbsaref.
More information is available on the associated GitLab issue.
