Subject: [PATCH] discount: use deterministic mangling

`discount` offers a randomized string mangling function which results in
non-deterministic output.

This commit disables the randomized mangling in favor of a deterministic
approach. `discount` has builtin support for this through the
`--debian-glitch` configuration flag.
