[Buildroot] [git commit branch/next] netsnmp: Make server and client installation optional

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=a387ff3837efca695c5449e0d0be1b9a7c9d7ee2
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/next

The netsnmp package consists of both a server and a number of client
tools, this makes the installation of both parts optional.

[Thomas:
  - Add explicit --enable-{agent,applications}, and use positive logic.
  - Remove "net-snmp" from the new Config.in option prompts, since
    they are already visible under the netsnmp package option.]
