check_mysql: Assume MySQL server by default (in replica check)
In the Debian Bug tracker (and then Github) a person pointed out,
that a MySQL server does not respond with a hint that is indeed the
MySQL software but only with the version string.
Which makes sense if one assumes to be the only implementation.
This commit changes the behaviour of the Replica check to assume
that the counterpart is a MySQL server if there are not hints that
it is a MariaDB server.
