net-snmp: fix compilation with GCC 14

[vortexilation]

Missing header & incompatible pointer type is now an error

Maintainer: @stintel
Compile tested: x86_64
Run tested: Test needed, test not done, since I am not using snmpd.

Description:

Functionalities wise not tested but seems to be passed compilation.
I am fairly new in github or git, assistance might be needed from developers.

Sorry for the last 2 failed PR attempt.

[stintel]

Was this submitted upstream?

[vortexilation]

No, only personal trial.

I don't think upstream will accept ieee802dot11.c module.

[vortexilation]

I am sorry need update, submitted the wrong changes.

@neheb
Please kindly review my new commit, as previously was the wrong changes.

Also How to squash the commit into one and push?.

[neheb]

git rebase -i HEAD~2

replace pick with s on the last commit.
git push --force

Make another PR. Reverting this brokenness.

@neheb
Thank you for approving my first contribution, I didn't get that error before, maybe because I am using glibc?, I will see what I can do about it.

[stintel]

Please always test using musl, this is the default libc for all but one target.

Ok, sorry for these.
