app-text/jabref: Switch to log4j-12-api:2, and make ebuild improvments

- Update to EAPI 8
- Enable tests
- Remove redundant java-utils-2 inheritance
- Update XDG desktop files database as appropriate
- Remove redundant src_compile after declaring CP_DEPEND and
  EANT_*_TARGET
- Ensure 'dodoc' target directory of src/txt/README is not affected by
  USE="doc"

+From f24492bff17f728bcf2b5a50069669ae08b8b372 Mon Sep 17 00:00:00 2001
+From: Yuan Liao <liaoyuan@gmail.com>
+Date: Sat, 19 Feb 2022 10:21:04 -0800
+Subject: [PATCH] Add JVM system properties and argument for tests
+
+The changes to system properties ensure that all paths the application
+may write to during the tests are not protected by the Portage sandbox.
+
+The extra argument added is required on Java 17+, but it should also be
+compatible with all Java versions that support the Java Platform Module
+System (JPMS), namely Java 9+.  On older Java versions, it is optional.
+On Java 8, however, including it in JVM arguments would cause an error.
