Describe the bug
Personal log doesn't work with --background

To Reproduce

sudo ./xmrig --algo=rx/0 --url=rx.unmineable.com:3333 --user=$coin:$address.$worker --keepalive --threads=2 --background --log-file=/home/user/my_log.log

No logs in "my_log.log
If I delete "--background" the records appear in the terminal and in the "my_log.log"

user@mst:~$ ls -l my_log.log
-rwxrwxrwx 1 user user 0 abr  3 09:17 my_log.log

Expected behavior
That the logs be saved in the custom log my_log.log and can use the --background option, so that nothing appears in the console

Required data

• XMRig version 6.21.2
• OS: Ubuntu 22.04
• CPU Intel Xeon

Workaround

replace personal log with --syslog

sudo ./xmrig --algo=rx/0 --url=rx.unmineable.com:3333 --user=$coin:$address.$worker --keepalive --threads=2 --background --syslog
