Subject: [PATCH] libobs: Use IOKit error code when polling hotkeys (OSX)

In case a system authentication prompt is open the actual error code
(via err_get_code) is kIOReturnExclusiveAccess on OSX 10.9; I'm not
100% sure if this makes the "if (!value)" part of the code obsolete,
but that code path shouldn't be triggered under most circumstances
anyway
