ui: Don't use '%default-port-encoding' to set the encoding of string ports.
* guix/ui.scm (right-arrow): Call 'set-port-encoding!' to set PORT's
encoding; remove use of 'with-fluids'. This is for compatibility with
Guile 2.2 where the encoding of string ports is not influenced by
%DEFAULT-PORT-ENCODING.
* tests/ui.scm ("show-manifest-transaction"): Likewise.
