python-utils-r1.eclass: _python_set_impls, add integrity check
Add integrity check for multi-inherits, i.e. ensure that PYTHON_COMPAT
has not changed between successive calls to _python_set_impls. If it did
(e.g. because of eclass+ebuild setting different values), then we abort
not to give surprising results to the user.
