Revert "glsl: Switch to disable-by-default for the GLSL shader cache"

This reverts commit 0f60c6616e93cba72bff4fbfedb72a753ef78e05.

Piglit and all games tested so far seem to be working without
issue. This change will allow wide user testing and we can decided
before the next release if we need to turn it off again.
