Replace "ptree" with maintenance fork

Because ptree 0.3.2 dependends on crates that have security advisories
(down the dependency chain), we depend on a fork of ptree now, which
updates these dependencies.
We hope that this resolves the advisories for us.

This patch shall be reverted as soon as ptree 0.4.0 (with updated
dependencies) is published.
