Bump libinjection version.

[wargio]

might break a lot of things, but is a good idea to update it to the latest version: https://github.com/client9/libinjection

@wargio Seems like this is the new repo for Libinjection:
https://github.com/libinjection/libinjection

Fixes should be there. Some are already fixed.
