Connection to Named Pipes fails when server and client are run
Reproduction steps:
1. Open the attached “IN-99790/Source/Client” project
2. Open the Build Settings window (File > Build Settings)
3. Build the Project
4. Launch the “IN-99790/Builds/Server/LinuxNamedPipeTest” executable through the terminal
5. Launch the Build through the terminal with {{-logFile {path}}} argument
6. Observe the terminal and log file outputs
Expected result: Both Server and Client successfully connect to the two named pipes and each sends and receives a single message without issue
Actual result: Neither Server nor Client successfully completes the connection to the named pipes because the Unity side has the issue where it is blocked.

Resolution Note:
The named pipe support is the class libraries was changed from using the underlying OS's named pipe support to using Unix domain sockets. This is not a change we plan on reverting.
To work around this P/Invoke into the OS's mkfifo API to create a named pipe.
See https://github.com/dotnet/corefx/pull/6833 for details on the change.
