Add function depthcharge_libpayload_build_path()

This function will return the correct build path for libpayload
built for depthcharge targets nyan and veyron. Without this
function, and using project_build_path() instead, LIBPAYLOAD_DIR
would be set to "$root/$BUILD/libpayload-depthcharge-nyan-big"
instead of the proper "$root/$BUILD/libpayload-depthcharge-nyan",
for example.
