gbproxy: Use a separate regexp for routing

Currently one regexp ('patching') is used for all matching.

This patch adds a second category 'routing' which is exclusively used
for SGSN selection. It also adds a corresponding VTY command:

  - match-imsi patching RE : MS related patching (currently APN)
  - match-imsi routing RE  : Select secondary SGSN on match only
  - no match-imsi          : Clear all filter expressions
