[Buildroot] [PATCH] package/piglit: Only support mesa and nvidia OpenGL provider

[Romain Naour]

Even if piglit could be used to test any OpenGl implementation, it's really a
mesa's project because it follow closely the mesa implementation (API).

Other OpenGl vendor (binary blob) are quickly out of date and incompatible with
piglit. Especially ARM OpenGl vendors such TI, Allwinner (sunxi) and rpi.

So introduce BR2_PACKAGE_PIGLIT_SUPPORTED_GL_PROVIDERS to list all supported
OpenGL providers. For now only mesa and Nvidia are supported.

Fixes:
