Quote liquibase.jar path in bash launcher

[nvoxland]

Description

The current liquibase bash script does not quote the liquibase.jar path, so it will not run if there is a space in the path to LIQUIBASE_HOME. It fails with a Error: Unable to access jarfile error.

This quotes the path so it works correctly

Repo Steps

1. Untar liquibase.tar.gz to a path containing a space in the filename
2. Run ./liquibase --version

The failing functional test is unrelated to this change, so can be ignored.

I confirmed that the command --version can be executed even if there are spaces in the LIQUIBASE_HOME path.
