bitbake: toaster: Amend regex for MySQL database URLs

The database URL detection doesn't admit a MySQL URL without a port.

As this is a common case (e.g. you would set the HOST to a mysql.sock
path if pointing at a local MySQL server, with no port setting),
amend the regex so it will correctly recognise paths, as well
as HOST:PORT URLs.
