GLContextImpl.setRendererQuirks(..): Use GLRendererQuirks.addQuirk(int), dropping usage of .addQuirks(int[] quirks, offset, len)

Directly adding a quirk allows dropping usage of erroneous fixed-sized int[] array for accumulated quirks.

If Mesa < 8.0 and software - or -
property 'jogl.fbo.force.nocolorrenderbuffer' is set,
set quirks:
- GLRendererQuirks.BuggyColorRenderbuffer
- GLRendererQuirks.NoFullFBOSupport (to disable MSAA)

GLFBODrawable always uses FBOMODE_USE_TEXTURE
if GLRendererQuirks.BuggyColorRenderbuffer is set.
