=dev-java/gradle{,-bin}-3.1: fail to compile/work

[tharvik]

=dev-java/gradle-3.1 fail to compile and =dev-java/gradle-bin-3.1 fail to work.

The comon error message is Could not initialize class org.fusesource.jansi.internal.CLibrary.

It happens when starting to use gradle, either during the build for bootstrapping or during normal use. From what I tried, it seems that the failing class is not linked during boot, installing dev-java/jansi-native do not solve it, maybe there is a way to replace the bundled one (if any) with the system version.

Due to lack of time and interest in Gradle, I had to take the recent pull requests in good faith without testing them. Over to you, @msva.

It's pretty strange.
At the time I created pullrequest with bumps to 3.1 both of them installed pretty fine.
And I'll recheck if they installs fine now, in few minutes...
