Add non_apex.exclude_shared_libs to cc

This can be used to add apex-specific shared_libs to a CC module. It
would be nice if we could have apex.shared_libs. But it would make code
much harder to follow because we need to record the shared_libs list as
"exclude list" for non-apex anyway.

  # check DTNEEDED for libapexsupport
  # only apex-variant should have the dependency
