QtCore: Remove std::mutex and std::condition_variable fallbacks

They existed because INTEGRITY hadn't yet been updated to the C++11
Standard Library, with a minor for broken MinGW cross-compilation builds
that forgot to enable gthreads support in libstdc++. The former appears
to have been since fixed and the latter is a massive toolchain
configuration mistake.
