[Piglit] [Patch v3 2/8] igt.py: Change an empty string to a list

[Dylan Baker]

Currently there is a function that in some cases could return '', but
the output is assumed to be a list. This patch ensures that it always
returns a list.

v3: - further simplify the function by using two return statements
      instead of a single return and assignment
