Fixed filesystem corruption issues

Browse Source 
Fixed:
filesystems were created with journaling disabled, now journaling is enabled
filesystem was mounted rw on boot, which prevented fsck from running
 - changed to ro, which then gets mounted as rw by systemd using the fstab file
 - added a fstab for the external boot devices that tries both usb and sd card
