ANDROID: Enable SVE support also for the microdroid crashdump kernel

Give that many of Android devices are now built with SVE on, the
crashdump kernel needs to support it.

The alternative of turning SVE off (ex: -march=armv8-a) for the
crashdump binary is rejected because it requires building bionic also
with SVE off.

Test: run microdroid, and echo c > /proc/sysrq-trigger
Flag: EXEMPT bug fix
