dev-perl/Package-DeprecationManager: Bump to version 0.170.0

Keywords restored from 0.150.0 as the added dependency in 0.160.0 is gone
again in 0.170.0, so we can pretend 0.160.0 never happened and this is a
straight bump.

0.160.0 will just be removed in a future commit because it introduced a
dependency cycle if Package-DeprecationManager 0.160.0 stabilized for
alpha, arm, ppc or x86 before namespace-autoclean-0.280.0 did.
