fs: Make the full directory path for the pid file and the control socket

Build systems should not attempt to create $runstatedir (or anything
under it).  Doing so causes warnings in packaging systems, such as in
Alpine Linux, as reported by Andy.

But unitd(8) can be configured to be installed under /opt, or other
trees, where no directories exist before hand.  Expecting that the user
creates the entire directory trees that unit will need is a bit
unreasonable.  Instead, let's just create any directories that we need,
with all their parents, at run time.
