[BUG] ob-shell: cmdline and stdin broken when used with TRAMP

[Felix Freeman]

When using TRAMP, ob-shell's :cmdline and :stdin header options are
broken on org-babel.

I've noticed that when those options are present, it takes other route
on ob-shell.el, but I lack the proper background to fix or debug it
further.

Probably cmdline is more complicated to get working right, but stdin
seems to do most things just fine (it creates the file within the remote
part) but isn't able to read it when needed.

I'm attaching:

- A file to test the functionality: test-tramp.org
- The backtrace: backtrace.el
- Emacs generated "current state": current-state.el
