dev-lang/python-exec: Bump to 2.2, needed for #568974

Bump to version 2.2 that makes it possible to symlink python-exec2-c
directly as wrapper. This is necessary to support wrapping
/usr/bin/python correctly on non-Linux systems where shebangs must only
reference real executables (rather than the Python script used so far).
