build: rename MOD vars to EXTRA vars

To make them less confusing, as they are extra dependencies, not files
that are specific to the module.

Commands used to search and replace:

    $ git grep -IFlz -e 'MOD_HDRS' -e 'MOD_OBJS' -- src |
      xargs -0 -I '{}' sh -c "printf '%s\n' \"\$(sed \
        -e 's/MOD_HDRS/EXTRA_HDRS/g' \
        -e 's/MOD_OBJS/EXTRA_OBJS/g' '{}')\" >'{}'"

Added on commit f5b1ccaad ("makefiles: move extra deps into new MOD
vars", 2022-05-07) / PR #5478.
