mail: Improve inbox display in aerc and notmuch

Added filtering by dump tag *or* folder to afew so that incoming mail
should automatically be filed exclusively in inbox or the dump for
notmuch.

Additionally changed the exception for inbox display from list to dump
tags in aerc, so that -- should there be a legitimate mailing list mail,
such as gitlab's pipeline reports -- they are still visible in inbox.
