Adapt package for framework v2

[schlessera]

Fixes #86

[swissspidy]

Could not open input file: vendor/bin/../../utils/make-phar.php

Where is that script located now?

Or should that test be removed?

[schlessera]

That script is now part of the wp-cli/wp-cli-bundle package and located at utils/make-phar.php in that package.

@schlessera Sounds like wp-cli/wp-cli-tests needs wp-cli/wp-cli-bundle as a dependency then:

@swissspidy No, I moved tests that create new Phars into the wp-cli/wp-cli-bundle repository. We should move this one too.
