Decrease stack usage in lexer.

Browse source 
We have only 92K of stack and using over 4K per frame is wasteful

	* grub-core/script/yylex.l (yyalloc), (yyfree), (yyrealloc): Declare
	as macros so that compiler would remove useless structure on stack.
	Better solution would be to fix flex not to put this structure on
	the stack but flex is external program.
