RetroAchievements: Delay calling LoadApprovedList

0c14b0c8a70799072ddccb648006914af7c62855 made Dolphin load a file from
the Sys folder the first time AchievementManager::GetInstance() is
called. Because Android calls AchievementManager::GetInstance() from
setBackgroundExecutionAllowedNative, this had two negative consequences
on Android:

1. The first time setBackgroundExecutionAllowedNative gets called is
   often before directory initialization is done. Getting the path of
   the Sys folder before directory initialization is done causes a crash.
2. setBackgroundExecutionAllowedNative is called from the GUI thread,
   and we don't want file I/O on the GUI thread for performance reasons.

This change makes us load the data from the Sys folder the first time
the data is needed instead. This also saves us from having to load the
data at all when hardcore mode is inactive.
