[Buildroot] [git commit] snmppp: add option to disable SNMPv3 support

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=4474809aa4b81fc234159e2555d5c0045e18692c
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Disabling SNMPv3 support also removes the dependency on OpenSSL, which is
pretty large (over 2 MB of uncompressed filesystem size on an ARM926 platform).

BR2_PACKAGE_SNMPPP_SNMPV3 defaults to yes for backward compatibility with
previous Buildroot releases, where SNMPv3 was always enabled.
