mesa: fix glPushAttrib(0) / glPopAttrib() error

If the glPushAttrib() mask value was zero we didn't actually push
anything onto the attribute stack.  A subsequent glPopAttrib() call
would generate a GL_STACK_UNDERFLOW error.  Now push a dummy attribute
in that case to prevent the error.

Mesa now matches nvidia's behavior.
