git p4: create p4/HEAD on initial clone

There is code to create a symbolic reference from p4/HEAD to
p4/master.  This allows saying "git show p4" as a shortcut
to "git show p4/master", for example.

But this reference was only created on the second "git p4 sync"
(or first sync after a clone).  Make it work on the initial
clone or sync.
