Following up on r1619413, mark the new enforce_consistent_revprop_caching()
test a WIMP, because it currently fails on platforms with named atomics
disabled in compile time.  We could probably tweak its expectations,
but the corresponding changeset is planned to be reverted (as per
http://svn.haxx.se/dev/archive-2014-08/0273.shtml), so this should be
a cheap way of making our buildbots green again.

Discussed in #svn-dev IRC.

* subversion/tests/libsvn_fs_fs/fs-fs-pack-test.c
  (test_funcs): Make the enforce_consistent_revprop_caching() test a WIMP.
