Support ebtable-legacy in allocd

cuttlefish_common.init selects which ebtables program to use, as
ebtables may not be available on all platforms, but instead may be
ebtables-legacy. Since we're calling popen using that program name, this
commit adds a method for choosing which version of ebtables to use with
a new flag, set when allocd is started.

The flag approach was chosen over just using a string to ensure that
there would be no unintended way to influence the arguments to popen,
since the program name can only be one of two choices.

These changes propagate to all users of the ebtables apis, which so far
is limited to only the wireless configurations.

Bug: 148823285
Test: make -j
Test: allocd &;
      launch_cvd --use_allocd;
      stop_cvd
