chore: don't compress binaries/libraries with upx (#1188)

upx allows to reduce the package size by some mega bytes, but also
considerably slows down the application start time.

This commit ditches upx, since we can re-gain those benefits (and even
increase them) by other means (e.g: minifying JavaScript).
