lib/attr: add nla utility functions for signed integers

Commit 7bb956501ccd58ed3bbffc59de996f056e178683 added nla functions for
s32. We preferibly add all signed integer operations at the same time.
Thus, also add s8, s16, and s64.

Also, previously the NLA_TYPE_MAX enum was not extended to have
NLA_S32. Fix that too.
