Project folder deletion while running build.sh

@DImuthuUpe I tried running the script at `scripts/build.sh`. However, the script deleted the whole folder where the repo was cloned. I took a peek into the script and there's this `rm -rf` at https://github.com/apache/airavata-mft/blob/master/scripts/build.sh#L22=

Probable solution:
- change the name of the target folder to something else instead of the main project folder name.

Start with scripts/build.sh and inspect the rm -rf command at the linked line, along with how its target folder is named. Confirm whether the target can resolve to the cloned project directory. Done means the build still uses its temporary target folder without deleting the repository; verify by running build.sh in a disposable clone.
