Usman Nadeem 405ad84793 Update hwasan test to fix failure on older Android API versions.
In Android API < 30 there is no HWAsan instrumentation support for globals
so the test fails if API < 30 or if the target triple does not specify the API version.

Add -triple=aarch64-linux-android31 to enable global instrumentation. This is the
same triple as is used in the RUN line for -fsanitize=memtag-globals.
