[COMMON][MARIADB] Force Galera Node address

Bitnami init script can automatically choose the node address (which is
the IP address of the container).
Unfortunately, this doesn't work when on dual stack as both IP addresses
with a space are given (see
bitnami/charts#4077).
This patch force the IP address so we can get rid of this issue
