Bug 1450839 - Exclude mochitest-errata.ini from test-disable.yml. CLOSED TREE

This file is not part of the build. (it's used to generate
generated-mochitest.ini)
What's tripping up this lint is this line:
 # [gl:0D6DE000] mozilla::gl::GLContext::raw_fDrawArrays: Generated unexpected GL_INVALID_OPERATION error. (0x0502)
This line is picked up as a false-positive, since the too-naive regex
(effectively /#.*\[/) interprets this as a skipped test.
