glcpp: Fix source numbers set with "#line LINE_NUMBER SOURCE_NUMBER"
Previously, the YY_USER_ACTION was overwriting the yylloc->source value in every action, (after that value had been carefully set by the handling of the #line directive). Instead, we want to initialize it once in YY_USER_INIT and then not touch it at all in YY_USER_ACTION.
