ports: Make BOARD default from BOARD_DIR in Makefile's.

This allows:

    $ make BOARD_DIR=path/to/board

to infer BOARD=board, rather than the previous behavior that required
additionally setting BOARD explicitly.

Also makes the same change for VARIANT_DIR -> VARIANT on Unix.

This work was funded through GitHub Sponsors.
