glsl/glcpp: Combine the two rules matching any character
Using a single rule here means that we can use the <*> syntax to match
all start conditions. This makes the catch-all rule more robust against
the addition of future start conditions, (no need to maintain an ever-
growing list of start conditions for this rul).
