Make Dropbear regex more compatible and simpler
Dropbear uses `strftime` `"%b %d %H:%M:%S` to print its timestamps, hence we know the day and time format, but the month could be localized. We hence allow any 3 word characters for it, and additionally simplify the day and time pattern into a single group.

Fix Dropbear filter when logging to STDOUT
Since Debian Bookworm, the distribution ships Dropbear with a native systemd service instead of the default upstream init.d service, and accordingly uses the `-F` and `-E` flags, to run it in foreground and have it logging to STDOUT instead of syslog.

As usual, timestamps and also the PID are now included by the log message emitted by Dropbear, in addition to the systemd journal log prefix.

The Dropbear filter hence does not match anymore. This commit adds the PID and timestamp as optional pattern between prefix and fail log text, to support Dropbear on Debian Bookworm and newer (and likely new versions of other distros) without breaking the old pattern when running Dropbear without `-E` flag.

Additionally, for performance reasons, this commit adds a `journalmatch` entry, matching Debian's and Fedora's `dropbear.service` with `dropbear` executable/identifier, the most likely match for a Dropbear systemd service.

df94ec4c52 filter.d/exim.conf: rewrite host line regex for all varied exim's log_selector states
Depending on Exim's log_selector settings, log lines may contain additional information about the connection. And also the line itself with the address of the remote host can vary greatly. But fortunately, all states can be found in the Exim code itself and taken into account. Makes it easier to add new regexps.
Closes #3263
