Add test7/test12/test14 in fexit_test.c and fentry_test.c to test the
fentry and fexit whose target function have 7/12/14 arguments.
And the testcases passed:
./test_progs -t fexit
$71 fentry_fexit:OK
$73/1 fexit_bpf2bpf/target_no_callees:OK
$73/2 fexit_bpf2bpf/target_yes_callees:OK
$73/3 fexit_bpf2bpf/func_replace:OK
