When more recent gcc ports are built without bootstrap, compiling libcc1
plugins results in errors similar to:

This is because gcc's own system.h header poisons these identifiers, and
the libcc1 plugins include <vector> after that. (Note that libstdc++ is
not affected because they seem to have implicitly included <vector>
already at that point.)
Fix it by telling system.h to include <vector> at the correct place, and
removing the explicit includes from libcc1plugin.cc and libcp1plugin.cc.
