Updated dolphin-emu package fixes security vulnerabilities

Dolphin Emulator includes a modified copy of the SoundTouch library at version 1.9.2. That version is subject to the following security issues:

• The TDStretch::processSamples function in source/SoundTouch/TDStretch.cpp in SoundTouch 1.9.2 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a crafted wav file (CVE-2017-9258)

• The TDStretch::acceptNewOverlapLength function in source/SoundTouch/ TDStretch.cpp in SoundTouch 1.9.2 allows remote attackers to cause a denial of service (memory allocation error and application crash) via a crafted wav file (CVE-2017-9259).

• The TDStretchSSE::calcCrossCorr function in source/SoundTouch/ sse_optimized.cpp in SoundTouch 1.9.2 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted wav file (CVE-2017-9260).

• Reachable assertion in RateTransposer::setChannels() causing denial of service (CVE-2018-14044).

• Reachable assertion in FIRFilter.cpp causing denial of service (CVE-2018-14045).

• Assertion failure in BPMDetect class in BPMDetect.cpp (CVE-2018-17096).

• Out-of-bounds heap write in WavOutFile::write() (CVE-2018-17097).

• Heap corruption in WavFileBase class in WavFile.cpp (CVE-2018-17098).

• Heap-based buffer overflow in SoundStretch/WavFile.cpp:WavInFile ::readHeaderBlock() potentially leading to code execution (CVE-2018-1000223).

The bundled copy of SoundTouch was updated to version 2.1.2, thereby solving theses issues in Dolphin Emulator.
