[issue8393] subprocess: support undecodable current working directory on POSIX OS

[STINNER Victor]

New submission from STINNER Victor <victor.stinner at haypocalc.com>:

In py3k, subprocess uses _posixsubprocess.fork_exec() function. This function uses surrogateescape error handler for most arguments, but not for the current working directory (cwd).

Attached patch uses PyUnicode_FSConverter() as done for other arguments. I don't know if PyUnicode_FSConverter() result is always a PyBytes, so I added an assertion. It should be fixed.
