Subject: [PATCH] selftests/seccomp: Fixed type mismatch warning

Forced cast of the variable passed to the get_uprobe_offset()
function either probed_uretprobe or probed_uprobe.

The solved warning is as follows:
  CC       seccomp_bpf
seccomp_bpf.c: In function ‘UPROBE_setup’:
seccomp_bpf.c:5175:74: warning: pointer type mismatch in conditional expression
 5175 |         offset = get_uprobe_offset(variant->uretprobe ? probed_uretprobe : probed_uprobe);
      |

Command to test it:
make -C tools/testing/selftests TARGETS=seccomp
