Issue: Bad behaviour for named pipe (mkfifo) 
Labels: bug,file-explorer


Issue Type: <b>Bug</b>

The presence of a named pipe (created via mkfifo on Linux) results in undesirable IDE behaviour; on (at least) Linux (possibly also macos)
```
mkdir x && cd x
mkfifo this-is-a-named-pipe
code .
```
You now have

Problems:
* the pull "doing something" indicator on editor tab never stops ... doing... - IMHO, it should not even attempt doing anything with pipes.
* "Unknown File Type" - yeah, it's a named pipe ;)
* Trying to delete the pipe from vscode results in the operation never completing

None of that is really breaking, and you'd be right in wondering why I would actually have named pipes in a directory (hierarchy) which vscode touches, but then ... 

I think the overall expectation is
* don't try to open named pipes
* perhaps show "Named Pipe" if you encounter one (`find -type p`)
* make delete work
