the code intended to filter out the software-renderer, but the
test as written was essentially a no-op.
the problem didn't happen most of the time because we had
updated egl.cfg to not even list the software renderer.
the test as written didn't generate a compile-time error
because String8 has a const char* cast operator; but the
end result was to compare pointers instead of the string
itself.
