Avoid decoding errors when extracting message ID from stdin

The mbox, am, and pr subcommands accept an mbox on stdin and extract
the message ID.  When stdin.read() is called, Python assumes the
encoding is locale.getpreferredencoding(False).  This may not match
the content encoding, leading to a decoding error.

Instead feed the stdin bytes to message_from_bytes(), which leads to a
decode('ASCII', errors='surrogateescape') underneath.  That's
sufficient to get the message ID from the ASCII headers.
