Fix the bug that when running on the PinePhone, sometimes the page with
progress would not appear. Thanks to Caleb for figuring it out!

Bump it so it finishes when running on the PinePhone.

* Only show the keyboard button if the page has a text input.
* Only show the keyboard layout dropdown if the on-screen keyboard is
  active.
* Remember if the user toggled the button, and use the same state on the
  next page with a text input (as opposed to always showing/hiding,
  depending on if there's a physical keyboard).
* Use the LVGL hidden flag to hide the object, not the vertical
  position.

The keyboard animation code was currently unused in ondev2. I think it
looks pretty cool in unl0kr when booting it up. But not sure how useful
it is during the installation, with the multiple pages we have here etc.
Remove it for now.

A follow-up patch will only show the keyboard layout dropdown if the
on-screen keyboard is visible. Swap it with the keyboard button, so the
button doesn't change its position when the dropdown appears.

Prepare to hide the keyboard button + dropdown for all pages that don't
have text input. Move the contrast button to the right of it, so it
doesn't change position when the keyboard button/dropdown show up.

Fix that it aborts here if a filesystem already exists:
  /dev/mmcblk2p1 contains a ext2 file system labelled 'pmOS_boot'
          last mounted on /mnt/install-boot on Thu Jan  1 00:00:50 1970
  Proceed anyway? (y,N)

For the steps where we can't properly calculate the progress (everything
except when copying the files basically), move the progress bar with a
fake progress based on time passed so it's still clear that the
installer is doing something.

Add the verbose initfs hook when -v is set.

Remove unrelated image files from other test in case they exist, so they
don't get copied from the tempdir inside the ondev2 dir into the
pmbootstrap chroot for building ondev2 from source.

Run 'make install' into the temp dir and set PATH so ondev2 can
successfully find its shell script ondev2-fstab-remove-boot-root.

Introduce a new env var OD2_BOOT_MOUNTPOINT_INSTALLER that allows
overriding the installer's boot mountpoint (usually /boot) in
test/run-test-host-losetup. This way we don't try to copy files from the
host's /boot partition.

It also fails when the format string is invalid, and that's more likely.
