Validate config parameter fix

[init-penguin]

Hello there!

I've found an error in -v / --validate-config behaviour and this code should be able to fix that.

In particular, python, afaik, doesn't have any capability to cast input arguments to boolean (so even if you would set --validate-config True it would be string value, not a boolean), thus Line 36 condition will fail anyway.

Now it is possible to use as a normal option without passing additional argument (like --version ie).

If you may, please, consider reviewing this promptly, 'cause we're using Yacron in kinda production environment and this type of validation is somewhat crucial for our CI/CD pipelines - our devs aren't careful enough to validate configuration on their own.

Thanks in advance.

Heh, sorry for that. I should have paid more attention to the PR that introduced this feature 🙈
