channels: Consider news files as UTF-8-encoded by default.

Partly fixes <https://issues.guix.gnu.org/57039>.
Reported by Pierre-Henry Fröhring <contact@phfrohring.com>.

Previously, news file would be read using the current locale encoding.
This could lead to a test failure in 'tests/channels.scm' (in a test
that expects some Unicode-capable encoding) in case tests were run in a
non-Unicode locale.

* guix/channels.scm (channel-news-for-commit): Make port for NEWS-FILE
UTF-8 by default.
