Liping Xu ddb4ce1040 update rsyslog log size conf (#15821)
Why I did it
For some devices whose log folder size is larger than 200M, for example, 256M, the LOG_FILE_ROTATE_SIZE_KB should be 16M. and
THRESHOLD_KB=$((USABLE_SPACE_KB - (NUM_LOGS_TO_ROTATE * LOG_FILE_ROTATE_SIZE_KB * 2)))
= $(( (VAR_LOG_SIZE_KB * 90 / 100) - RESERVED_SPACE_KB)) - (NUM_LOGS_TO_ROTATE * LOG_FILE_ROTATE_SIZE_KB * 2)))
= $(( (256M * 90 / 100) - 4096)) - (8 * 16M * 2)))
the result would be a negative value

Work item tracking
Microsoft ADO (number only):
24524827
How I did it
Add a case for 400M, if the log folder size is between 200M and 400M, set the log file size to 2M

How to verify it
Do cmd "sudo logrotate -f /etc/logrotate.conf" on DUT which val/log folder size is 256M, and check the syslog.
