nla_put_uint()

Hi, Jakub. Thank you for reminder.

I read the commit log and learned the advantages of this helper.
But it seems that the support for corresponding user-space helpers
hasn't kept up yet, e.g. can't find a helper like nla_get_uint in
latest libnl.

Add it, then.

Danielle added one to libmnl:

https://git.netfilter.org/libmnl/commit/?id=102942be401a99943b2c68981b238dadfa788f2d

Intention is to use it in ethtool once it appears in a released version
of libmnl.

Thanks, that is a good example.
