Few things:
* Discord binary has RUNPATH not RPATH set
* patchelf uses RUNPATH if it already exits, so deps end up in RUNPATH
* RUNPATH isn't searched for plugins or transitive deps
* ..badness results
Despite this, it currently seems to work-- with the caveat
that it has a little bar on top complaining about how
"it looks like your installation is corrupt".
This fixes that warning and does some minor cleanup.
