Android: Keep folder and shortcut grants, re-take the folders we use

Pruning now only runs when the config was really read: when the memory
stick isn't reachable at startup (an unmounted SD card, or right after
boot), NativeInit falls back to defaults and the recent list is empty, so
every recent game's grant looked unused and was released.

Grants for the memory stick, the Games tab folder and pinned folders are
re-taken at every startup. That moves their persisted time up, so they're
the last the system drops if we ever reach its limit. The new time is
written out with the next grant change, which is also the only time the
system prunes.

Home screen shortcuts can't be enumerated, so the 64 most recently
created or launched are remembered in a new [Shortcuts] section of
ppsspp.ini, and their grants are kept. ShortcutActivity runs without the
config loaded, so it queues them in SharedPreferences until the next
startup saves them.
