[fedora-java] New macro - %gradle_build

[Mikolaj Izdebski]

For your information, I've just pushed XMvn 2.5.0 to rawhide. It has
improved Gradle integration, which allowed implementing %gradle_build in
javapackages-tools.

The %gradle_build macro works just like %mvn_build, except it invokes
Gradle instead of Maven.  It also accepts the same arguments.

Once project is built with %gradle_build, it can be installed by
invocation of %mvn_install.  All other standard %mvn_* macros can also
be used with %gradle_build.

I will try documenting this as time allows, but until it's done you can
see spec files of other packages as example how to use this new macro.
