kbuild: Remove stack protector flags

Browse Source 
-fstack-protector-strong is controlled by the in-tree
CONFIG_STACKPROTECTOR_STRONG config option.  If the flag is set without
the config option, scst fails to build:
ERROR: modpost: "__stack_chk_fail" [scst/src/scst.ko] undefined!

-fstack-clash-protection is disabled in the kernel's Makefile due to an
incompatibility with randomize_kstack_offset.

Fixes: 86d3d4bb1d ("kbuild: Enable additional compiler warnings")
