If CONFIG_KASAN=y, powerpc:allmodconfig fails to build with the following
error.
Error: External symbol 'memset' referenced from prom_init.c
The problem was introduced with commit 41b7a347bf14 ("powerpc: Book3S
64-bit outline-only KASAN support"). So far, with CONFIG_KASAN=y, only
__memset was accepted as valid external symbol in prom_init_check.sh.
Add memset as well to fix the problem.
Fixes: 41b7a347bf14 ("powerpc: Book3S 64-bit outline-only KASAN support")
