get-wget-lua should bail out earlier if dependencies aren't available

Script bailed out at the last minute because pkg-config wasn't found (then the correct ssl wasn't found) - which is a silent failure earlier in the script.

If you detect dependencies earlier this could bail out earlier and save time and downloads.

I've setup a few instances and I've lost a few crawls because of the ARM Warrior not having rsync inside the Dockerfile. I'm going to submit a PR for the Warrior but I agree that this pipeline should check for dependencies so that future crawls don't break.

missing dependencies list

im getting few compile errors, and lost more than half hour for compiling ...

Yes, this is painful on ARM hardware.

If you want to have deps checked manually, I'd prefer a separate script as it's very distro dependent how you do that.

I agree that that there shouldn't be a compile if it's know it's going to fail, but demonstrated that that can be predicted reliably.

This is a candidate for the next build script. Could someone test it on ARM.
