SanitizerBlacklist: Use spelling location for blacklisting purposes.

When SanitizerBlacklist decides if the SourceLocation is blacklisted,
we need to first turn it into a SpellingLoc before fetching the filename
and scanning "src:" entries. Otherwise we will fail to fecth the
correct filename for function definitions coming from macro expansion.
