vty cfg: move 'ipa-name' from 'msc' to 'hlr' section

during code review, I completely overlooked this:

We've added the 'ipa-name', which identifies the MSC on the GSUP link to the
HLR, under the 'msc' section, while all other GSUP/HLR related config is under
the 'hlr' section.

Before we roll that out in a release, move it over to 'hlr'.
