Running jgit on Fedora >= 30 results in an immediate failure¹:
$ jgit --version
/usr/bin/build-classpath: Could not find xz-java Java extension for this JVM
/usr/bin/build-classpath: error: Some specified jars were not found
Error: Could not find or load main class org.springframework.boot.loader.JarLauncher
Skip the jgit tests if 'jgit --version' fails. This way we'll begin
running them again once the issue is resolved -- without having to make
any further changes to the git package.
Also exclude jgit on i386 arch, as upstream eclipse has dropped support.
We could adjust the conditional to only exclude on Fedora >= 30 and
i386, but the added complexity is not worth the effort.

It is useful to check the output of the test suite for skipped tests.
This reveals tests which may have missing BuildRequires or other issues.
Doing so can be tedious due to the many legitimate tests we skip. Keep
a list of patterns matching tests we skip intentionally.
To use this list to process a build.log, run something like the
following:
$ egrep '# SKIP|skipped:' build.log | egrep -v -f git.skip-test-patterns
There should be no output. Any output should be checked and the tests
fixed or added to the skip patterns file.
