openrc: Add logrotate support for openrc systems

[Kawanaao]

Optional logrotate support for openrc based systems that have logrotate

[Kawanaao]

Fully tested on my system, the configuration files perform the task, the only question is the size of the log files, if according to #521 the log size within the normal range will be lower than 50 MB

reading config file /etc/logrotate.d/scx
acquired lock on state file /var/lib/misc/logrotate.status
Reading state from file: /var/lib/misc/logrotate.status
Allocating hash table for state file, size 64 entries

rotating pattern: /var/log/scx/*.log 1048576 bytes empty log files are not rotated, only log files >= 4194304 bytes are rotated, no old logs will be kept
considering log /var/log/scx/scx.log

  log needs rotating
rotating log /var/log/scx/scx.log, log->rotateCount is 0
dateext suffix '-20240820'
glob pattern '-[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]'
renaming /var/log/scx/scx.log.1 to /var/log/scx/scx.log.2 (rotatecount 1, logstart 1, i 1), 
old log /var/log/scx/scx.log.1 does not exist
log /var/log/scx/scx.log.2 doesn't exist -- won't try to dispose of it
skip copying /var/log/scx/scx.log to /var/log/scx/scx.log.1
truncating /var/log/scx/scx.log
