Fix for mariadb local path

When running docker-compose with mariadb the following message will appear:

ERROR: for mariadb  Cannot create container for service mariadb: Invalid volume spec "mariadb": Invalid volume destination path: 'mariadb' mount path must be absolute.
ERROR: Encountered errors while bringing up the project.

This commit fixes the issue.
