As already discussed upthread, anyone who wants the path can get it from
`pwd` or local equivalent --- and that mechanism is robust (as long as
the directory move doesn't happen while any particular instance of the
script is running).  I don't see why we should go out of our way to
provide a bad substitute for pwd.

BTW, I note that some post-startup uses of DataDir have crept back in,
in places like utils/adt/dbsize.c.  I'll be sure to clean those up
before release...
