[v0.1.3] Fix interaction with Oxide and password echoing

Several fixes that improve interaction with Oxide after #6 was fixed.

• Mountpoint path checking was fixed (was detecting false positives)
• Faster startup (removed old display glitch workaround that caused a delay)
• Important security fix: Do not echo keyboard keypresses to journal. (Previously, the password was accessible through journalctl)
