Tests that (almost) always fail

[cboulay]

• MINGW - internal loguruthreadnames skip
• MacOS - internal reuseport on ipv6 multicast - skip
• pushpull benchmarks in MSVC win often segfault

The first 2 don't test LSL code directly so I have excluded the problematic config on the problematic target platform.

I managed to reproduce a segmentation fault from the pushpull benchmark test locally. It happens here:

liblsl/src/sample.cpp

Line 81 in 7e61a2e

if (x < factory->storage_ || x >= factory->storage_ + factory->storage_size_)

It happens at the very end of the test case, as the outlet is going out of scope, triggering its cleanup:

lsl::stream_outlet::~stream_outlet() > lsl_destroy_outlet(...) > ~stream_outlet_impl() > lsl::factory::~factory()

During ~factory, this line

liblsl/src/sample.cpp

Line 470 in 7e61a2e

if (cur != sentinel()) delete cur;

cur is already nonsense.
