GSUP: include terminating nul in inter-MSC source/destination name

Before, I was testing with osmo-hlr patch
I01a45900e14d41bcd338f50ad85d9fabf2c61405 applied, but that patch is currently
in an abandoned state.

This is the counterpart implemented in osmo-msc: always include the terminating
nul char in the "blob" that is the MSC IPA name.

The dualities in the formats of routing between MSCs is whether to handle it as
a char*, or as a uint8_t* with explicit len (a blob).

In the VTY config to indicate target MSCs for inter-MSC handover, we have
strings. We currently even completely lack a way of configuring any blob-like
data as a VTY config item.

In osmo-hlr, the IPA names used for routing are currently received as a char*
which *includes* the terminating nul char. So in osmo-msc, if we also always
include the nul char, it works.

Instead, we could just send the char* part without the nul char, and apply
above mentioned osmo-hlr patch. That patch would magically match a name that
lacks a nul with a name that includes one. I think it is better to agree on one
format on the GSUP wire now, instead of making assumptions in osmo-hlr on the
format of the source/target names for routing. This format, from the way GSUP
so far transmits the IPA SERNO tag when a client attaches to osmo-hlr, happens
to include the terminating nul char.
