RFR [XS]: 8238947: tools/jpackage tests fail with old rpmbuild versions

[Baesken, Matthias]

Hello, please review this small change adjusting the minimal rpmbuild version  of tools/jpackage tests .

Currently the tools/jpackage tests, for example jdk/test/jdk/tools/jpackage/linux/AppCategoryTest.java fail on older distros with rpmbuild tools < 4.10 .
This can be seen on Suse Linux (SLES11) with rpmbuild 4.4 and on RedHat 6 with rpmbuild 4.8 .
For example, rpmbuild returns an unexpected "rpmbuild: no spec files given for build" when calling :

> rpmbuild --eval=%{_target_cpu}
> x86_64
> rpmbuild: no spec files given for build

Probably we should check for at least rpmbuild version 4.10 when executing the tests (on Suse Linux 12 and on RedHat 7+ we have rpmbuild 4.11 or higher).
