osmo_ss7: introduce notion of configurable 'quirks'
A quirk is an implementation work-around in order to establish
interoperability with another implementation, either a buggy one or
one that follows a different interpretation of a given spec.
For now, we introduce a first quirk affecting when we (in ASP role)
send an ASP-ACTIVE message to the SG.
Closes: OS#5145
