AppImage: Improve binary stripping

Slightly reduces file size, improves build speed and makes build more
reproducible.

The .comment section contained GCC version information which could cause
different build output from just a minor update in GCC. The information is not
needed so we strip this.

The strip command was invoked using xargs, spawning a new process for each file.
This is inefficient as xargs can correctly run the strip command with multiple
file names.
