boot: Consider non-bootable partitions
Any 'bootable' flag in a DOS partition causes boostd to only scan
bootable partitions for that media. This can mean that extlinux.conf
files on the root disk are missed.
Put this logic behind a flag and update the documentation.
For now, the flag is enabled, to preserve the existing behaviour of
bootstd which is to ignore non-bootable partitions so long as there is
at least one bootable partition on the disk. Future work may provide a
command (or some other mechanism) to control this.
