Streamline persistent_cache_test for testing efficiency (#6601)

Browse source 
Summary:
This test was written like a stress test, using up to 3x26GB
RSS memory during parallel 'make check'. Now, while this code is mostly
dormant, I've made the "for Travis" versions of the expensive tests the
canonical versions and disabled the expensive versions. This has the
side benefit of removing some arbitrary conditional compilation.

For unknown reason, the super expensive tests were gated on
Snappy_Supported, which appears to be irrelevant, so I removed it.

The tests can be fixed / improved / migrated to stress test if/when they
are deemed important again.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6601

Test Plan:
make check + CI

./persistent_cache_test Before:
...
[==========] 10 tests from 2 test cases ran. (114541 ms total)
[  PASSED  ] 10 tests.
YOU HAVE 1 DISABLED TEST

After:
...
[==========] 3 tests from 2 test cases ran. (1714 ms total)
[  PASSED  ] 3 tests.
YOU HAVE 10 DISABLED TESTS
