Teach parallel_emerge to uninstall packages.

Browse Source 
Currently, parallel_emerge doesn't know how to handle uninstall actions, so it
actually installs packages when it should be uninstalling them. This patch
fixes that.

TEST=sudo ./parallel_emerge -uDNv hard-host-depends, and make sure it
     uninstalls nih-dbus-tool, which is blocked by hard-host-depends
BUG=none
