Subject: [PATCH] plugins/check_mysql*.c: define our own default MySQL port.

The MYSQL_PORT constant used to be defined in mysql.h, and was used as
the default port in the two plugins check_mysql and check_mysql_query.
Now that mysql.h no longer defines that constant, our plugins fail to
build against newer versions of MySQL and MariaDB.

Since MYSQL_PORT used the "default port" on the local system, it
actually was not the best choice as the default for the check plugins:
when monitoring remote MySQL servers, the usual default of 3306 is
more likely to be correct than whatever the local server happens to be
listening on.

As a result, we fix the issue by defining our own constant, called
CHECK_PORT_DEFAULT, as "3306" at the top of both check_mysql.c and
check_mysql_query.c. The existing uses of MYSQL_PORT have been changed
to use the new CHECK_PORT_DEFAULT.

This change is backwards-incompatible: any users who compiled in a
MYSQL_PORT other than 3306 and who were running their checks on the
same server as the database will now need to specify that port
explicitly.

Closes: https://github.com/monitoring-plugins/monitoring-plugins/issues/1508
