Fix "missing plugin" error in linux chrome.
On linux first check succeeded, while next one will fail and no plugin information got returned.
So, I am inverting logic a little bit. IFF check for plugin file succeeded, we omit all
subsequent for this file in the process.

BUG=none
TEST=Check PDF plugin is working in Chrome linux sandbox, and no PDF plugin is in Chromium build.
