meta-parsec/layer.conf: Insert addpylib declaration

Yocto mickledore introduced the addpylib directive for explicitly adding
layer paths to the PYTHONPATH.

Standalone OEQA test suite discovery does not require this directive but
it is required to import test cases from other layers, e.g. to extend
and modify the test cases.
