inferior: Keep the store bridge connected.

Previously, each 'inferior-eval-with-store' would lead the inferior to
connect to the named socket the parent is listening to.  With this
change, the connection is established once for all and reused
afterwards.

* guix/inferior.scm (<inferior>)[bridge-file-name]: Remove.
(open-bidirectional-pipe): New procedure.
(inferior-pipe): Use it instead of 'open-pipe*' and return two values.
(port->inferior): Adjust call to 'inferior'.
(open-inferior): Adjust to 'inferior-pipe' changes.
(close-inferior): Remove 'inferior-bridge-file-name' handling.
(open-store-bridge!): Switch back to 'call-with-temporary-directory'.
Define '%bridge-socket' in the inferior, connected to the caller.
(proxy): Change first argument to be an inferior.  Add 'reponse-port'
and call to 'drain-input'.  Pass 'reponse-port' to 'select' and use it
as a loop termination clause.
(inferior-eval-with-store): Remove 'socket' and 'connect' calls from the
inferior code, and use '%bridge-socket' instead.
