fix #193

It's not clear how this fixes your issue, can you add an explanation in the PR for why the absolute path with a space in it works but the relative path with a space does not?

@MarshallOfSound
This PR actually solves the fact that the spawn of the codesign MacOS utility has the correct fullpath to the packaged app.

The previous version would simply try to codesign the packaged app in the current working directory (which is wrong of course) because of wrong arguments passing.
Which causes official Electron boilerplates like (https://www.electronforge.io/templates/vite-+-typescript) to fail to pass the signing step when using yarn make.

When notarizing, using a relative path for the codesign parameter and an application name with spaces causes the notarization to fail. This issue does not occur with absolute paths.
