support/scripts/br2-external: declare missing local variables

Commit b14b02698 (core/br2-external: restore compatibility with old
distros) switched to using 'eval' to emulate associative arrays, for
those distros too old to have bash-4+.

In so doing, it forgot to declare the new local variables in the
respective helper functions.
