perlPackages.NetSNMP: add patch to support newer SHA algorithms 

The aged perlPackages.NetSNMP library does not support modern SHA algorithms for authentication.
It's possible to enable support for these newer protocols with a patch.
The patch is taken from the OpenBSD ports tree:
https://github.com/openbsd/ports/blob/master/net/p5-Net-SNMP/patches/patch-lib_Net_SNMP_Security_USM_pm
It enables support for SHA 224, 256, 384, and 512.
Tests are also include in the patch for these additional algorithms.
