test: enable addons test to pass with debug build

Currently when running configure with the --debug option in combination
with the tests (./configure --debug && make -j8 test) there are a few
addon tests that fail with error messages similar to this:

=== release test ===
Path: addons/load-long-path/test
fs.js:558
  return binding.open(pathModule._makeLong(path), stringToFlags(flags),
mode);
                 ^

Error: ENOENT: no such file or directory, open
'/nodejs/node/test/addons/load-long-path/build/Release/binding.node'

    at run (bootstrap_node.js:382:7)
Command: out/Release/node
/nodejs/node/test/addons/load-long-path/test.js

This commit allows for the tests to pass even if the configured build
type is of type debug.
