fs_mgr: Add fs_mgr_overlayfs_is_setup()
Provide a means to determine if overlayfs is currently active with
fs_mgr_overlayfs_is_setup(). Search for current clues in the system
that the overrides are in play. If /mnt/scratch/ is mounted, that
may be enough of a smoking gun because the resource itself may
interfere with operations.
Related to update_engine calling this function to reject performing
an OTA as its operations are incompatible with the overrides.
Test: adb-remount-test.sh
Bug: 120034852
