scripts: use `trap` to make sure old files always restored

In this commit, we fix an issue I observed on my machine after updating
many command line/dev utilities.

I observed that if the script failed for w/e reason, then the old files
weren't properly restored.

The repro on my machine is something like:
  1. Shutdown docker, make sure the daemon isn't accessible.
  2. Run `mac sqlc`. The script should fail.
  3. Observe that the files in your local working tree are still
     altered.

We fix this by using the `trap` command, [which is basically like Go's
`defer`, but for bash
scripts](https://tldp.org/LDP/Bash-Beginners-Guide/html/sect_12_02.html)!
