S3 Invalid entry inserted into ~/.bashrc when non-distributed installation is used

Build tested: 1.4.0-1

This issue occurs only when S3 (both localStorage or S3) storage option (option #4) is selected on a non-distributed installation over multiple nodes. I tested on a 1um2pm stack. The ~/.bashrc file on non-pm1 nodes (um1 and pm2 in my test stack) has the following entry at the end of the file.

. /usr/local/mariadb/columnstore/bin/

This entry is invalid and it cause the following error when the user logs in:

root@127.0.0.1's password:
Last login: Tue Sep 10 19:27:28 2019 from 10.0.2.2
-bash: .: /usr/local/mariadb/columnstore/bin/: is a directory

While postConfigure is being executed, I monitored PM2's .bashrc file. The entry seemed to have been inserted from the point where postConfigure tries to start up the stack.
