bpftool: fix libelf.h not found error

When build host machine is not installed with elfutils-libelf-devel, it
throws compile error "libelf.h: No such file or directory". Fix missing
headers file by including path ${STAGING_INCDIR_NATIVE} via CFLAGS variable.
Use headers file from ${STAGING_INCDIR_NATIVE} instead of host machine.

Error:
| libbpf_internal.h:19:10: fatal error: libelf.h: No such file or directory
