Added CFI blacklist to handle indirect calls to assembly functions

Since libmpeg2dec is a static library, both CFI and non-CFI variants
will be built and linked accordingly.
Hence it is not enabled explicitly now.
If it is used as a shared library in the future, we'll need to
explicitly re-enable CFI in the build file.

Test: mpeg2dec with test input
