[Piglit] [PATCH 01/18] cmake: Add options BUILD_GLES{1, 2} tests [v2]

[Chad Versace]

Default value for each is OFF.

Before this patch, Piglit automatically built the GLES1 tests if libEGL
and libGLESv1_CM were found. Ditto for GLES2 and libGLESv2. If these
libraries were installed on the system, it was impossible to disable the
tests.

This patch adds options to explicitly enable the tests.

v2: Fix typo GLES1 -> GLES2.
