Delete a dummy ChangeLog in ‘make distclean’.

Browse Source 
‘make distcheck’ from git may create a dummy ChangeLog file in the
build directory.  Delete this on ‘make distclean’, but don’t delete
a real ChangeLog (generated by the gen-ChangeLog rule).

* Makefile.am (distclean-local): Delete ChangeLog if it is the dummy
  created to pacify automake.
