refactor: rpi_boot: use chroot to run flash-kernel, ditch double reboot strategy

[Bodong-Yang]

Description

This PR introduces one-step firmware install strategy to rpi_boot to deprecate the previously used double steps firmware update strategy. It also includes some internal refinements in rpi_boot.

New features

1. support flash-kernel directly in post-update phase with chroot to standby slot.
2. now if system-boot partition is not mounted, rpi_boot will try to mount it.
3. rpi_boot now allows extra partitions after partition ID 3.

Check list

• test file(s) that covers the change(s) is implemented.
• local test is passed.
• test on real machine is passed.

Other changes

1. otaclient_common.linux: implement new subprocess_run_wrapper, which supports chroot.
2. otaclient.boot_control.common: implement a plain version of mount.
