Fix build error on linux

[csclyde]

When running the script on Linux, it would fail to create a build. This was because it would throw an unhandled exception when looking for the hl.exe file. The exception is now caught, so the script can not proceed to actually creating the Linux build.

Closed with no comment... is there something different you'd like to see with this? I started my own thing based on redistHelper, because there are a lot of linux problems with redistHelper. Let me know if I can help with the linux build on this one...

Sorry, I just noticed your message here! I don't actually see any real reason for this PR to be closed 🤔

Maybe the try catch could be a little bit closer to the actual exception source (which I guess is findFiles here?). I re-open it: please tell me if you want to change anything, I will just merge it otherwise.

@deepnight Hey, I kept working on this fix for Linux, and it sort of spiraled out into its own thing here:

I don't yet have 100% of the functionality of your redistHelper (still need setting icons and signing windows exes). But it's pretty close, and it works great on Linux. It's close to working on Mac too, I just need a better test machine to get all the shared libs fixed.

For this PR, I can either just move the try/catch down a little bit like you suggested, or we can maybe merge the two projects somehow.

@deepnight Hey there, I've updated my tool so that it works on all Win/Mac/Linux. Feel free to pull over the .dll, .so, and .dylib files if you please. I've made sure, especially on mac, that they all are set up correctly to look for local executable. My tool also now sets windows icon, file permissions on mac/linux, and creates a run.sh script for Linux so that a package will work perfectly on Steam for Linux.
