Rework the shell quoting of remote checksumming

Instead of getting rid of pipes.quote, use pipes.quote and get rid of
the manually entered toplevel quotes.  This should properly escape
backslashes, quotes, and other characters.

Also fix the new checksumming python "one-liner" for csh.
ansible_shell_type needs to be set to csh.

Fixes #10363
Fixes #10353
