There is some overlap with #51371 |

A lot of the failures are asserting at #63877 was intended to fix these issues and it appears they did on iOSSimulator, but we got a false positive from CI when it came to devices. |

A newline was incorrectly added to the script that executes xharness, causing the script to return a 0 exit code even if there was a crash. This caused CI to report a pass no matter what. System.IO.Tests was the only suite found where this had an impact. Contributes to dotnet#67853

tvOS has a MAX_PATH of 104 characters on domain sockets, and a 90 character value for GetTempPath. That gives us only 14 characters to play with, and temp filenames are 12 characters long. We cannot afford the `CoreFxPipe_` prefix on tvOS, with our tiny character path budget. Check whether this fixes some or all of dotnet#67853 and dotnet#51390 too.

Reopening. This issue is a collection of entirely unrelated issues, and likely not even tvOS specific. We have dozens of ActiveIssue for this bug number, will close when those are handled. |

This is actually a mix of three distinct bugs:

Gotta use remote executor to use SetCurrentDirectory to fix the UNC & drive letter tests, apparently. |

* Use SetCurrentDirectory on tests which use an unrooted path on non-Windows out of the app's working directory, which is readonly on some platforms. Closes: #67853 * Just blank out mkfifo tests
