Allow NextCloudPi to run/update on Linux Deploy containers in Android

[DesktopECHO]

Hello,

Turns out that NextCloudPi runs very nicely on Android in a Linux Deploy container. The changes in this PR are the minimim needed to accmodate running in Linux Deploy. There are other things needed like SysV initscripts, but that can be fixed externally.

If these changes can be accomodated NextCloudPi will update on Android like all other supported devices, and a fork won't be necessary to prevent breakage from updates.

• Video of the deployment at work
• Linux Deploy image: ncd12.tgz

Cheers, D.
