grub: fix load module all_video failed

Browse Source 
While using oe-core toolchain to strip grub module 'all_video.mod',
it stripped symbol table:
--------------
root@localhost:~# objdump -t all_video.mod

all_video.mod:     file format elf64-x86-64

SYMBOL TABLE:
no symbols
--------------

It caused grub to load module all_video failed.
(This module will be loaded by defalut which configed in grub.cfg)
--------------
grub> insmod all_video
error: no symbol table.
--------------

Tweak strip option to keep symbol .module_license could workaround
the issue.
