Makefile.am: Always include rule to make org.libvirt.api.policy

When running 'make dist' on a system without policykit, we currently
fail. This is because $(srcdir)/access/org.libvirt.api.policy is in
EXTRA_DIST, however, the rule to generate the file is conditional
whether we build with polkit or not.
