[mythtv-users] Mythimport fix for new Mariadb versions

[Stephen Worthington]

I have just used my mythimport program for the first time since
upgrading to Ubuntu 22.04 and found a problem where the latest version
of the Mariadb mysqldump program (as run by the mythexport daemon) is
now putting a warning message at the top of the output .sql files:

WARNING: Forcing protocol to  TCP  due to option specification. Please
explicitly state intended protocol.

To fix this, I have updated mythimport to ignore any "WARNING:"
messages.  The new version is available from my web server:
