verify_ptable_flag: dos primary partitions use ptable_uuid map for flag

Curtin currently special-cases verifying MSDOS 'boot', 'extended'
and 'logical' flags. This ignored primary DOS partitions. When
verifying partition flags on a MSDOS primary partition use
ptable_uuid_to_flag_entry map as we do for GPT partitions.

I don't know if this is a possible scenario, but is it possible to have a boot type partition that is not marked as bootable ?

For example, suppose we have this type of configuration:

sfdisk_info_dos = {
            "label": "dos",
            "id": "0xb0dbdde1",
            "device": "/dev/vdb",
            "unit": "sectors",
            "partitions": [
               {"node": "/dev/vdb1", "start": 2048, "size": 8388608,
                "type": "80"},
               {"node": "/dev/vdb2", "start": 8390656, "size": 8388608,
                "type": "83"}]
}

In that scenario the boot check would fail, because we will not have the bootable key, but the MBR_TYPE_TO_CURTIN_MAP would find the expected "boot" flag as we want.

But do we want to have a boot partition that is not marked as bootable ? I think this scenario can happen if we provide a custom sfdisk_info dict to the function, but I don't know if that can actually happen, or if it does, if it is a problem.

Good catch, and actually I need to remove the 0x80 from the MBR table, as it's a flag, not a table type. I'll add a unittest covering this scenario.

Drop 0x80 boot flag from MBR_TYPE map, it's a PART_ENTRY_FLAGS value only.

Ensure boot flag is captured even on logical partitions

 Nice one Ryan, this looks good. one minor question/suggestion about whether we can always expect a 'type' key from block.get_partition_sfdisk_info and how we should handle it.
Otherwise +1

@Chad

Yes, each partition entry has a type.
