Fresh repo clone build fails

[neeme-praks-sympower]

Steps:

1. clone https://github.com/NeuronRobotics/nrjavaserial/
2. ./gradlew jar

Expected result: a successful build.

Actual result: build failure as gradle.properties is a symlink to /home/hephaestus/gradle.properties.

Workaround: replace the contents of gradle.properties with:

ossrhUsername=
ossrhPassword=

The problem was introduced in this commit.

I have just learned how to auto-release to sonatype so i will be migrating that process over to nrJavaSerial, this issue will be fixed in that process.

Well, the fix is easy so why not just fix it now? In your local environment, you can still continue using symlink, gradle.properties is in .gitignore anyway.
