selftests: kselftest_harness: Fix compile warning

Browse Source 
Do not confuse the compiler with a semicolon preceding a block. Replace
the semicolon with an empty block to avoid a warning:

  gcc -Wl,-no-as-needed -Wall -lpthread seccomp_bpf.c -o /.../linux/tools/testing/selftests/seccomp/seccomp_bpf
