glsl: Properly lex extra tokens when handling # directives.
Without this, in the <PP> state, we would hit Flex's default rule, which
prints tokens to stdout, rather than returning them as tokens. (Or, after the
previous commit, we would hit the new catch-all rule and generate an internal
compiler error.)
With this commit in place, we generate the desired syntax error.
This manifested as a weird bug where shaders with semicolons after
extension directives, such as:
#extension GL_foo_bar : enable;
would print semicolons to the screen, but otherwise compile just fine
(even though this is illegal).
Fixes Piglit's extension-semicolon.frag test.
This also fixes the following Khronos GLES3 conformance tests, (and for real
this time):
invalid_char_in_name_vertex
invalid_char_in_name_fragment
