dev-java/rxtx: Fix various build errors for Java 11+ and others, EAPI 8

- Fix compiler errors due to -Werror=format-security
- Fix Javadoc generation errors
- Replace 'javah' with 'javac -h' for JDK 10+
- Attempt to fix some random, nondeterministic build-time errors that
  were speculated to be caused by parallel 'make'.  Those errors are not
  always reproducible and may go away during a retry, which might have
  stopped some users (including the commit author himself) from
  reporting them.  Another random error popped up when the new ebuild
  revision was being tested, hence a fix that forces sequential build is
  attempted in the hope to prevent probable random errors.
