Update JSR166 tck tests.

The following tests have been omitted because they are
unsupported :

- Atomic8Test.java
- CompletableFutureTest.java
- ConcurrentHashMap8Test.java
- DoubleAccumulatorTest.java
- DoubleAdderTest.java
- ForkJoinPool8Test.java
- ForkJoinTask8Test.java
- LongAccumulatorTest.java
- LongAdderTest.java
- SplittableRandomTest.java
- StampedLockTest.java
- ThreadLocalRandom8Test.java
- ThreadPoolExecutor9Test.java

A package declaration has been added to all files (package jsr166;)
and the base-class JSR166Test has been changed not to rely on features
that aren't available on android / junit in the android environment.

We also avoid using junit4 style TestSuite declarations. While the CTS
test runner handles them properly usually, it trips over itself when it
encounters a failure and tries to run each test in an invidual process
and fails each test for no good reason (needs investigation on the CTS
side of things)

bug: 20628776

(cherry picked from commit 5da8b2b3cac51f0f592a5e1941bd84eade9648cd)
