[Piglit] [PATCH] add test for initial texture state

Current Mesa fails to produce GL_INVALID_ENUM in glGetTexLevelParameteriv
and segfaults when passed NULL.
---
It's kind of pointless to pass null to a glGet* function like this,
but I couldn't find
any language in the spec about ignoring NULL pointers, which seems like the
sane thing to do.
