[Piglit] [PATCH 2/2] cmake: only install files for APIs that are built

[baker.dylan.c at gmail.com]

From: Dylan Baker <baker.dylan.c at gmail.com>

This configures piglit to only install the following features if they're
enabled:
- profiles
- generated files
- shader_test,program_test,{shader stage},ktx,cl,etc

The basic idea is that if one doesn't build OpenGL, then the OpenGL
tests and profiles shouldn't be installed, and likewise for OpenCL.

This patch continues to combine OpenGL and OpenGL ES, install both if
any are selected. While it could be split more it would be a very
invasive change.

There are two benefits to this. First, it reduces the install foot print
by not install features that are incomplete. Second, and more
importantly, it doesn't install profiles that are unsupported, which
means that piglit will die with an error message equivalent to "no such
profile", rather than dying while trying to compile the profile. This
can be a source of confusion for those who are not familiar with piglit.

I have verified that running "piglit run quick cl foo -c" produces the
same output before and after (this will run quick.py and cl.py)
