[oe] [meta-oe][PATCH] bpftool.bb: Disable SECURITY_CFLAGS

[Khem Raj]

We do not pass CFLAGS to build and fortify sources needs some
optimization to be enabled, its better to reset the additional flags and
let the build system add them as it needs

Fixes build failures like
tools/include/tools/libc_compat.h:11:21: error: static declaration of 'reallocarray' follows non-static declaration
|    11 | static inline void *reallocarray(void *ptr, size_t nmemb, size_t size)
|       |                     ^~~~~~~~~~~~
