dropbear: move failsafe code out of base-files

The sender domain has a DMARC Reject/Quarantine policy which disallows
sending mailing list messages using the original "From" header.

To mitigate this problem, the original message has been wrapped
automatically by the mailing list software.
Failsafe code of dropbear should be in the dropbear package not the
base-files package.
