Reduce installer size by file types

Auditors: @aekeus

Fix #7896

By ignoring by file type we can remove a lot of the redundant rules and catch things automatically as we add deps. I found this script on SO which lists all file types recursively

`find . -type f | perl -ne 'print $1 if m/\.([^.\/]+)$/' | sort -u | gvim`

After getting that list I exluded the things I think we need, and then
bisected when there was a problem starting the browser.
