Installer errors should suppress stack trace & bug report URL

[getaaron]

General troubleshooting steps

• [x] I understand that if I ignore these instructions, my issue may be closed without review.
• [x] I have retried my command with --force.
• [x] I ran brew update-reset && brew update and retried my command.
• [x] I ran brew doctor, fixed as many issues as possible and retried my command.
• [x] I have checked the instructions for reporting bugs.
• [x] I made doubly sure this is not a checksum does not match error.

Description of issue

Installing Acrobat Reader fails. The issue is in the source installer, not homebrew cask (same issue occurs when running the installer manually).

The error text from installer contains the most helpful error message, but it's bundled in between a bunch of irrelevant red text and a stack trace with a suggestion to file a bug report:

I suggest that if we download an installer successfully and it outputs an error, we can suppress the stack trace / prompt to file a bug and more prominently feature the installer error text.

This would match the error experience of running the GUI installer:

Command that failed

brew cask install adobe-acrobat-reader

Output of command with --force --verbose --debug
