Use static asan runtime for musl

Browse Source 
Use static asan runtimes for musl binaries to match glibc binaries.
The static asan runtime also requires libclang_rt.asan_cxx.a.  Unlike
most other runtimes the asan runtimes need to expose the symbols
from the runtime to allow intercepting calls to malloc, new etc.

Test: m USE_HOST_MUSL=true aidl_unittests && out/host/linux-x86/testcases/aidl_unittests/x86_64/aidl_unittests
Test: sanitize_test.go
