Explicitly configure ASPs asp-clnt-* as role=asp & sctp-role=client

Until recently, the asp-clnt-* ASPs, which have specific handling in osmo_sccp_simple_client_on_ss7_id(),
were being always forcedly set to sctp-role CLIENT by code in that
function.
This prevented user of that API from explicitly configuring the ASP as
"sctp-role server" through the VTY as the option would be overwritten silently.

Now, the sctp-role from config is followed if the ASP is
defined/configured through the VTY (not dynamically created at the time
osmo_sccp_simple_client_on_ss7_id() is called).

Since the default for a VTY-specified ASP is to be in "sctp-role
server", the config files need to be updated to properly configure the
ASP to be in "sctp-role client", which is the desired mode here.

Same applies for "role", where the default is SG but it is actually used
as "ASP" here.
