sys-apps/coreutils: Rev bump to address multiple test failures

- Running test suite with FEATURES=usersandbox is no longer supported
  due to various sandbox issues. (bug #413621, #439574, #629660)

- Due to sandbox failures previously disabled tests
  re-enabled. (bug #415487)

- tests/ls/readdir-mountpoint-inode test failure fixed. (bug #353164)

- "caps" USE flag description more specified. (bug #617702

- Tools/programs/libraries used in test suite now listed in
  DEPEND="test? (...)" which requires re-keywording for some
  architectures.
