Add missing pm.* properties in property_contexts

Certain pm.* properties, which are especially needed for
Go-targets, are not listed in property_contexts.
Init will not be able to set these properties on bootup
without the correct selinux contexts assigned to the
properties.

BUG: 111738816

Test: In selinux-enforcing mode, on bootup, these
      properties are now correctly set by init.
