ci: fix infinite loop on wait-up step

[wellwelwel]

Currently, the tools/wait-up.js test only recognizes an error when the MySQL Server returns a connection error, but if there is another type of error, it continues the loop infinitely:

node-mysql2/test/common.js

Lines 35 to 38 in 2419c49

	if (err.code !== 'PROTOCOL_CONNECTION_LOST' && err.code !== 'ETIMEDOUT' && err.code !== 'ECONNREFUSED') {
	console.log('Unexpected error waiting for connection', err);
	process.exit(-1);
	}

This PR sets a maximum limit of 5 minutes if the connection is not established.

Reviewing this step (CI) on all OS systems, the time takes between 1 second and ~2 minutes, so I've chosen to set the limit at twice the longest time.
