[Linux] Failed to initialize output

[Kazunekit]

Hello, I discovered that a change made after commit 94e2bad has broken obs in it's ability to find modules. This only happens on a clean install.

As mentioned, this only happens on clean install. When doing an update, make install just copies more files into the obs-plugins directory. This is how the directory looks after and update:

[ADcorpo]

Same problem here, obs looks for plugins beginning with "lib" only. Could be fixed temporarily by renaming all plugins by their names beginning with "lib".
