[jdk11u-dev] RFR: 8179317: [TESTBUG] rewrite runtime shell tests in java

[Christoph Langer]

This is a backport of JDK-8179317 and also includes the fix JDK-8247741. Backporting this test fix is a prerequisite for #1554.

I had to resolve a few places. Also, test/hotspot/jtreg/runtime/TLS/testtls.sh is not part of jdk11u-dev, so I skipped it.
