dev-lang/python-3.13.3-r1: fix forkserver for Solaris

multiprocessing forkserver method was not enabled on Solaris, causing
the provided compileall.py script to error out (no use of try/except or
inspection whether forkserver is exists it performed).  Add a patch to
add a missing include, and ensure Python's build uses a reasonably
recent standards level so definitions can be found.
