[Buildroot] [git commit branch/next] netsnmp: Add option for using minimal internal SSL code

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=415d42e12f36d8b0ea48fcf415d80eca2a7a5cae
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/next

Add option for enabling a minimal internal copy of OpenSSL usable for USM
security. It will not enable the usage of SNMP over (D)TLS.

[Thomas: use 'else ifeq' to avoid having another nested ifeq ... endif
block.]
