Enable memslot_modification_stress_test and memslot_perf_test in ARM64
(second patch). memslot_modification_stress_test builds and runs in
aarch64 without any modification. memslot_perf_test needs some nits
regarding ucalls (first patch).

memslot_perf_test uses ucalls for synchronization between guest and
host. Ucalls API is architecture independent: tests do not need know
what kind of exit they generate on a specific arch.  More specifically,
there is no need to check whether an exit is KVM_EXIT_IO in x86 for the
host to know that the exit is ucall related, as get_ucall() already
makes that check.

Change memslot_perf_test to not require specifying what exit does a
ucall generate. Also add a missing ucall_init.

These tests need to be added below the aarch64/* tests and in alphabetical
order.
