Change sysctl_add_oid use to SYSCTL_ADD_OID

[ngie]

Summary

sysctl_add_oid was changed in base/head@r310051 to take a label
parameter. SYSCTL_ADD_OID doesn't require the label parameter since its
inception, thus it's a backwards compatible solution for adding sysctl
oids.

I'll bump the port version at commit time.

Bump PORTREVISION is enough, no need to touch PORTEPOCH

Thank you for pointing this out <3! This was what I was curious about because the Porter's Guide didn't note this nuance explicitly.

Since 215353 is maintainer timeout'd. If you have confirmed this works on supported versions other than -CURRENT, I approve this change.

This change works on ^/stable/10 as well:

This change should work with all supported versions since SYSCTL_ADD_OID has been formalized for many years:

These patches implement dynamic sysctls. It's possible now to add
and remove sysctl oids at will during runtime - they don't rely on
linker sets. Also, the node oids can be referenced by more than
one kernel user, which means that it's possible to create partially
overlapping trees.

Add sysctl contexts to help programmers manage multiple dynamic
oids in convenient way.

Please see the manpages for detailed discussion, and example module
for typical use.

This work is based on ideas and code snippets coming from many
people, among them:  Arun Sharma, Jonathan Lemon, Doug Rabson,
Brian Feldman, Kelly Yancey, Poul-Henning Kamp and others. I'd like
to specially thank Brian Feldman for detailed review and style
fixes.
