[Siddhi Runner] -Dapps and -Dconfig fails with relative paths

[pcnfernando]

Description:
When we use relative paths as values for -Dapps/-Dconfig system arguments while starting Siddhi Runner, the corresponding functionalities fail.

Affected Product Version:
Siddhi Runner 5.1.0-m2

Steps to reproduce:

• Copy a Sample Siddhi file(SampleApp.siddhi) into SIDDHI_RUNNER_HOME/wso2 directory.
• Go to SIDDHI_RUNNER_HOME/bin directory and execute the following command.
  ./runner.sh -Dapps=../wso2/SampleApp.siddhi

When I run config changes locally using -Dconfig=./configurations.yaml it gives the following error. Moreover, when I run this config change in docker level, even when I gave the absolute path using Env -Dconfig=$HOME/configurations.yaml it gave the same error.
