[issue21772] platform.uname() not EINTR safe

[STINNER Victor]

STINNER Victor added the comment:

Here is a different but similar patch for _syscmd_uname():
- use os.fsdecode() to use the locale encoding instead of latin-1
- use subprocess.DEVNULL to redirect errors to /dev/null
- use "with proc:" to ensure that the subprocesss is cleaned in case of error
