[OE-core] [PATCH] oeqa/runtime/context.py: ignore more files when loading controllers

[André Draszik]

When loading controllers as (external) modules, the code currently
tries to load all files ending with .py. This is a problem when
during development using an editor that creates a lock-file
in the same directory as the .py file, as the lock file is
typically called '.#xxxx.py'.
Python will try to load the lock file and fail miserably with
an exception:

    The stack trace of python calls that resulted in this exception/failure was:
    File: 'exec_python_func() autogenerated', lineno: 2, function: <module>

         0176:        try:
         0177:            obj = getattr(module, target)
    Exception: ImportError: No module named 'oeqa.controllers.'

Simply ignore those when collecting the list of files to try
to load.
