remote: Print output and error stream in ‘remote-eval’.

Previously, anything written by the remote process to its output and error
ports was lost.  Now it’s properly transferred and displayed.

* guix/remote.scm (trampoline): Direct current output and error ports to a
string output port; return the port’s content in addition to the return value
of ‘primitive-load’.
(%remote-eval): Expect output/error string from ‘read-repl-response’ and
display it line by line.
