In commit da77c23, getuto "made quiet mode more quiet". It did this by piping the output of some gpg calls to a grep pipe, that filtered out any "expected warnings" in the form of no user IDs emitted by keys.openpgp.org, while mostly leaning on gpg --quiet to be quiet. In commit 15fcac9, getuto added -q to grep, with the note "Also, use grep -q to honour --quiet". This meant that grep was instructed to emit zero output if at all possible, and is intended to use for scripts that want to check the return code of grep to see whether matches were found. (getuto does NOT check this.) Given this is incorrect use of grep, we instead just redirect all stdout and stderr to /dev/null. It is semantically identical to what we already do, but with one less fork+exec and the intent is far clearer.
quiet mode silences all output, as made more obvious by the previous change. This isn't really appropriate for einfo status messages, though, even if it is fine for gpg output itself. Redirect our einfos to a temporary fd so we can capture them and preserve them. Fixes portage being entirely silent about the fact that it is running the trust helper, leading to people thinking portage itself is hanging forever if getuto itself has issues.
