purism/librem_bdl: Convert to variant setup

Convert the purism/librem13v1 to a variant setup, in
preparation for adding the librem15v2 board as a new variant.
The Librem 13 v1 and Librem 15 v2 are nearly identical, so
this minimizes new code to add support for the latter.

Also update the URL in board_info to an archive.org link.
