Uninstall a package asynchronously in a subprocess. When both parallel-install and ebuild-locks FEATURES are enabled, it is essential for the ebuild-locks code to execute in a subprocess, since the portage.locks module does not behave as desired if we try to lock the same file multiple times concurrently from the same process for ebuild-locks phases such as pkg_setup, pkg_prerm, and pkg_postrm.
