Review request for mesos, Bernd Mathiske and Till Toenshoff.


Added some variation in filename extension.

Also switched from `os::system` to `os::shell` so we can suppress benign stderr output from
`tar` (`tar: Removing leading '/' from member names`).

Bugs: MESOS-3579

Repository: mesos


GNU tar-1.28 and earlier can relatively randomly misidentify
compressed files as uncompressed ones, and will then fail when
unpacking. Avoid compressed tar files in some tests where we know we
directly call the tar system command (in mesos-fetcher in this case).

Diffs (updated)

  src/tests/fetcher_cache_tests.cpp ac5ad6acfcf60b7094ec45f64bed164b4dc3f8bd 
  src/tests/fetcher_tests.cpp 99c494a2167ea9ec94e63d92980df17a4089f95a 



`make check` and verified test does not fail in at least 17500 iterations.
