Fix syscall kld example

[fernape]

Summary

PR: 255936

The syscall kld example does not build.

Test Plan

• Apply patch
• make
• dmesg | grep syscall should show something like syscall loaded at 210

[gbe]

Should be fine, but since it is a src change I added @jilles for src review and approval.

54–56

The comments are now redundant.

Thanks!

As this is a small fix to the EXAMPLE, is it necessary to bump .Dd at commit time?

This is not a man page and it does not have a .Dd.

Oops! Sorry, the original PR mentioned SYSCALL_MODULE(9) man page, but there is only the path to the example not the code itself.

Thank you all for the review.
