Under GCC 4.9, fix the warning due to missing -fno-strict-aliasing:

samples/seccomp/user-trap.c:50:2: warning: dereferencing type-punned pointer will break strict-alias
ing rules [-Wstrict-aliasing]
samples/seccomp/user-trap.c:83:2: warning: dereferencing type-punned pointer will break strict-alias
ing rules [-Wstrict-aliasing]
