tmpfiles: add separate fragment for stuff we copy from .extra/ into /run/systemd

Let's move copying out the PCR signature/key into its own tmpfiles
snippet.

And then let's add support for copying out the profile + os-release
information systemd-stub now places in the invoked initrd.

That way these four pieces of information are available even after the
initrd→host transition.
