Subject: [PATCH] fix build error on flex-2.5.37

Patch-Mainline: no

New flex version 2.5.37 introduces build error like this

[  420s] grub_script.yy.c: In function 'yy_scan_bytes':
[  420s] grub_script.yy.c:2296:17: error: comparison between signed and unsigned integer expressions [-Werror=sign-compare]
[  420s] ./grub-core/script/yylex.l: At top level:
[  420s] grub_script.yy.c:2351:13: error: 'yy_fatal_error' defined but not used [-Werror=unused-function]
[  420s] cc1: all warnings being treated as errors

This patch ignore the two diagnostic pragmas as a temporal fix, hope
someone could dig into it and get the root cause.
