[c-bordon]

Issue: #692

I was able to replicate the error reported by the community user and apply the proposed fix with satisfactory results.

Before the fix:

root@Debian-Buster:~# /var/ossec/bin/wazuh-control start
2021/12/30 18:51:27 wazuh-modulesd: ERROR: (1241): Invalid day format: 'yes'.
2021/12/30 18:51:27 wazuh-modulesd: ERROR: (1235): Invalid value for element 'wday': yes.
2021/12/30 18:51:27 wazuh-modulesd: ERROR: (1202): Configuration error at 'etc/ossec.conf'.
wazuh-modulesd: Configuration error. Exiting

After the fix:
