docs: remove documentation of MESA_PRIVATE_CMAP

Browse Source 
This is used in the Mesa GLUT implementation, which has been separated
out into its own repo, and is largely abandoned in favour of FreeGLUT.

So let's not try to document MESA_PRIVATE_CMAP, as it's just going to
confuse users.

When sharing the root colormap, Mesa may be unable to allocate the
colors it needs, resulting in poor color quality. This can happen when a
large number of colorcells in the root colormap are already allocated.
To prevent colormap sharing in GLUT, set the **MESA_PRIVATE_CMAP**
environment variable. The value isn't significant.
