samples/seccomp: fix 31 bit build on s390
On s390 the flag to force 31 builds is -m31 instead of -m32 unlike
on all (?) other architectures.
Fixes this compile error:
HOSTCC samples/seccomp/bpf-direct.o
cc1: error: unrecognized command line option "-m32"
make[2]: *** [samples/seccomp/bpf-direct.o] Error 1
