[Piglit] [PATCH] all.py: fix extension/version testing when wflinfo fails

[Brian Paul]

If wflinfo is not installed or fails, the wfl_info.gl_extensions value
will be the empty set.  Similarly, the gl_version, glsl_version, etc.
will be None.

In those cases, return True from the gl_extension_supported() and
is_feature_directory_supported() functions so that we don't skip any
subdirs.

This is only relevant when PIGLIT_FILTER_DIRECTORIES is set.
