guix: inferior: Fix the behaviour of open-inferior #:error-port....I'm looking at this as the Guix Data Service uses this behaviour to record and
display logs from inferior processes.
* guix/inferior.scm (open-bidirectional-pipe): Call dup2 for file descriptor
2, passing either the file number for the current error port, or a file
descriptor for /dev/null.
* tests/inferior.scm ("#:error-port stderr", "#:error-port pipe"): Add two new
tests that cover some of the #:error-port behaviour.
inferior: Support querying package replacements....I'm looking at this to help with adding support for looking up package
replacements to store in the Guix Data Service.
* guix/inferior.scm (inferior-package-replacement): New procedure.
* tests/inferior.scm ("inferior-package-replacement"): New test.

inferior: Make sure test refers to guile@3.0....* tests/inferior.scm ("inferior-package-inputs"): Compare with
GUILE-3.0-LATEST since that's what 'lookup-inferior-packages' returns.

repl: Fix exception handling for interpreted code....The 'stack' variable could be #f when code is interpreted, which in
practice happens when running in "legacy" mode--i.e., when
'open-inferior' invokes "guile" instead of "guix repl".
* guix/repl.scm (send-repl-response)[handle-exception]: Check whether
STACK is true before passing it to 'stack->frames'.
* tests/inferior.scm ("&inferior-exception, legacy mode"): New test.
