feat: rotate jmwalletd logs

[theborakompanioni]

TBD.

!! Does not work as expected yet - jmwalletd keeps writing to the rotated file !!

Uses savelog to rotate /var/log/jam/jmwalletd_stdout.log.
Invoked via cron at midnight on every second day (0 0 */2 * *).

Eventually dinit has support for it natively–let's see what comes out of davmac314/dinit#121.

How to test?

TBD.

I don't know much about this project but Seems like this PR is blocked due to fail to find "a good Solution". I suggest use s6-log. Thats read from stdin and write to file and support automated log rotation without cron. Also it's available on most distributions (such as Alpine, Debian, Ubuntu) via s6 package.

Hey @mobin-2008, sorry for the late reply. Thanks so much for following up on this and the valuable information - I did not know about s6-log and will take a look!
