Dockerfile.mariadb - use included healthcheck (#26) 
* Dockerfile.mariadb - use included healthcheck

MARIADB_MYSQL_LOCALHOST_USER=1 creates the mysql@localhost user that the healthcheck uses with --su=mysql.

`--innodb_initialized` was chosen as a fairly basic test to ensure that any crash recovery is complete.

* Update Dockerfile.mariadb

with connect so ensure we are running on the final tcp instance rather than any temporary instance.

Using innodb_initialized as well to show of that more than one test is available, and the recovery time of innodb is a aspect that can be forgotten by those that don't frequently do mysql/mariadb admininstration.

* Update mysql/Dockerfile.mariadb

use implicit path

HEALTHCHECK

This is an example set of prototypes for enabling HEALTHCHECK behavior in select official images.

This repository is not actively maintained and only exists as a reference in implementing your own HEALTHCHECK which meets your particular needs more accurately than these generic examples possibly could. Resulting images are not actively built and pushed to a Docker Registry (and the FROM lines are likely even outdated).

See the HEALTHCHECK FAQ entry for the rationale for why these don't get added to the official images directly.
