arm32: kaslr: Avoid using the -fpic and fno-pic parameters together

hulk inclusion
category: bugfix
bugzilla: 188368 https://gitee.com/openeuler/kernel/issues/I6EEK7
CVE: NA

--------------------------------

Avoid using conflicting compilation parameters during compilation,
so we move -fpic from KBUILD_CFLAGS to CFLAGS_KERNEL to avoid
using -fpic and fno-pic parameters together.
