pmbootstrap install --ondev: new option (MR 1946)

Browse source 
Add initial support for the on-device installer in pmbootstrap. Let
pmbootstrap create a regular split image, then prepare a new installer
rootfs and copy the previously generated rootfs image into the installer
rootfs. Put the installer rootfs into a new image, with reserved space.

There is more to do from here, such as disabling the generation of the
user account when using --ondev. But this requires support in
postmarketos-ondev first, so let's build that iteratively.
