Add unixtime option

Add an option to return the expiration date in unixtime (time since
epoch).

  ./check_expire -H domain -u

It's particularly useful for alerting or monitoring systems that do
their own calculation based on the metric they receive (and not based on
exit codes).

For instance you can use the following in zabbix 5.4:
- item: check_expire["-H","{HOST.CONN}","-u"]
- trigger: last(/check_expire["-H","{HOST.CONN}","-u"])-now()<2592000

Where 2592000 is 30 days in seconds.

## Zabbix configuration
For monitoring systems that do not rely on exit codes but on calculation mechanism based on the metric they receive you can use the `-u` option that will only return the expiration date in unixtime format.
For instance, you can use the following in zabbix 5.4:
* item: `check_expire["-H","{HOST.CONN}","-u"]`
* trigger (30 days before expiration): `last(/check_expire["-H","{HOST.CONN}","-u"])-now()<2592000`
Where `2592000` is the number of seconds in 30 days.
