tests: Updated gtest/logging.cc to print log rather than fail.
Previously the `GTestExitLogger.log` function utilized GTest's
`ADD_FAILURE_AT` macro. This meant, whenever `GTestExitLogger.log` were
called, the calling test would be fail. This is problematic when
trying to test code we expect to fail (i.e., when testing the error
handling code is working correctly). Therefore, the `log` function now
writes to stderr.
The `GTestExitLogger` class is used by the `panic` and `fatal` loggers
when running GTests. Instead of callnig `exit(1)` they throw a GTest
exception, which can be captured in a test using
`EXPECT_ANY_THROW(expection_thrower())`. Catching and verifying error
logs can be done via:
```
testing::internal::CaptureStderr();
/*
* "exception_thrower()" is a method we'd expect to call `fatal` or
* `panic`, and therefore exit the simulation with a non-zero exit
* code. When running via GTest, an exception is thrown instead.
*/
EXPECT_ANY_THROW(exception_thrower());
EXPECT_EQ("<error message>", testing::internal::GetCapturedStderr()));
```
