gtest: upgraded package to upstream

Upgraded dev-cpp/gtest to version 1.7.0 on amd64, arm, x86

Changes for 1.7.0:

* New feature: death tests are supported on OpenBSD and in iOS
  simulator now.
* New feature: Google Test now implements a protocol to allow
  a test runner to detect that a test program has exited
  prematurely and report it as a failure (before it would be
  falsely reported as a success if the exit code is 0).
* New feature: Test::RecordProperty() can now be used outside of the
  lifespan of a test method, in which case it will be attributed to
  the current test case or the test program in the XML report.
* New feature (potentially breaking): --gtest_list_tests now prints
  the type parameters and value parameters for each test.
* Improvement: char pointers and char arrays are now escaped properly
  in failure messages.
* Improvement: failure summary in XML reports now includes file and
  line information.
* Improvement: the <testsuites> XML element now has a timestamp attribute.
* Improvement: When --gtest_filter is specified, XML report now doesn't
  contain information about tests that are filtered out.
* Fixed the bug where long --gtest_filter flag values are truncated in
  death tests.
* Potentially breaking change: RUN_ALL_TESTS() is now implemented as a
  function instead of a macro in order to work better with Clang.
* Compatibility fixes with C++ 11 and various platforms.
* Bug/warning fixes.
