Skip ramdump when running Microdroid with GKI as kernel
The android15-6.6 GKI defconfig doesn't have CONFIG_KEXEC_FILE enabled,
which means that we can't load Microdroid crashkernel. While we are
going to look into enabling this option for android16 GKIs, in the
meantime we will disable the crashkernel for Microdroid VMs that run
with android15-6.6 GKI as guest kernel.
