pmb.parse.bootimg: Add preliminary support for header v2 (MR 2194)

Browse source 
This includes setting header_version="2" as well as dtb_offset
according to the input boot.img when header v2 is detected.

Also adds the following previously missed deviceinfo_attributes:

* "header_version"
* "bootimg_custom_args"

And fixes failing tests now that header_version is always parsed from
boot.img files.
