base-files: upgrade: add case to export_bootdevice

The factory uboot of the Turris Omnia boots with "root=b301", and we
instruct new users to sysupgrade from there (e.g. method 1, step 7).
Currently, this will fail with "Unable to determine upgrade device".
Add a new case to export_bootdevice, which parses the hex argument.

Fixes commit 2e5a0b81 ("mvebu: sysupgrade: sdcard: keep user added ...")
