[jdk8u-dev] RFR: JDK-8290832: It is no longer possible to change "user.dir" in the JDK8 [v2]

[Sergey Bylokhov]

> This is the request to revert the fix for [JDK-8194154](https://bugs.openjdk.org/browse/JDK-8194154) integrated to the [openjdk8u342](https://github.com/openjdk/jdk8u/commit/5fcfb7acbe340c8347bd47413a36dd0b1e267dc1)
> 
> The fix for [JDK-8194154](https://bugs.openjdk.org/browse/JDK-8194154) disabled the possibility to change the "user.dir" property.
> Changing the "user.dir" was not recommended from the beginning but it was not forbidden, so there are some old applications that rely on the old behavior. 
> 
> For compatibility reasons, it would be good to restore the old behavior.
> 
> Note that the test is simplified and saved under a different name, now it will check just the possibility to change the 'user.dir' using a simple path and name.
