Reduce the required shader version for the team-color mask shader to
GLSL 1.10. As a result we loose the invariance guarantee for produced
vertex data, but in our case that ''probably'' doesn't matter.
As a result of this change, non-compliant OpenGL implementations which
''claim'' GLSL 1.20 support (but don't provide it), will be able to work
again.

Replace the usage of the depecrated ftransform() function with an
equivalent expression along with the invariance guarantee. Let the
shader compiler deal with optimising this expression.
