emulators/dolphin-emu: set LLD_UNSAFE
Prevent Dolphin from linking using lld as it fails with errors like:
/usr/bin/ld: error: cannot preempt symbol: alcOpenDevice
defined in /usr/local/lib/libopenal.so
referenced by OpenALStream.cppOpenALStream.cpp.o:(OpenALStream::Start())
due to preemption of symbols with protected visibility in a shared object.
See also PR #219089 for more details.
