fstab-generator: use more appropriate checks for swap and device availability
We always should use the same checks when deciding whether swap support and mounting of devices is supported. Hence, let's make fstab-generator's logic more similar to the usual logic we follow: a) Look for /proc/swaps and no container support before activating swaps. b) Look for /sys being writable befire supporting device mounts.
