polkit: fix /etc/polkit-1/rules.d permissions

The recipe installs /etc/polkit-1/rules.d as polkitd:root 0700, but
polkit's own tmpfiles.d entry declares it as root:polkitd 0750:

  d /etc/polkit-1/rules.d 0750 root polkitd - -

As a result, systemd-tmpfiles changes the ownership and mode of the
directory at every boot, and on a read-only root filesystem it fails
with:

  systemd-tmpfiles[241]: fchownat() of /etc/polkit-1/rules.d failed: Read-only file system

The polkitd:root 0700 ownership was added to avoid rpm conflicts with the
polkit-group-rule-* packages, which no longer install into /etc since
commit d5e90541f8.

Match upstream instead. This is also the stricter setting, as polkitd
can read the rules but cannot modify them.
