Close memory leak in lexer.

Browse source 
Simply call talloc_strdup rather than strdup, (using the talloc_parent
of our 'state' object, (known here as yyextra).

This fix now makes glsl-orangebook-ch06-bump.frag 99.97% leak free:

	total heap usage: 55,623 allocs, 55,609 frees

Only 14 missing frees now.
