LOG: [Clang][Sanitizers] Expect test failure on {arm,thumb}v7

Summary:
Versions of LLVM built on {arm,thumb}v7 appear to have differently
configured pass managers, which causes restrictions on which sanitizers
we may use.

As such, expect failure of the recently added "sanitize-coverage.c" test
on these architectures until we can investigate armv7's restrictions.
