UnitTestFrameworkPkg/UnitTestLib: Move print log into cleanup

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2805

If a unit test fails with an exception or an assert, then the
CmockaUnitTestFunctionRunner() is terminated and the logic
that follows the invocation of the unit test is skipped.  This
currently skips the logic that prints log messages.

Move the print of log messages to the end of the function
CmockaUnitTestTeardownFunctionRunner() that is guaranteed to
be executed when a unit test completes normally or is
terminated with an exception or an assert.
