fix distcheck

[Ben Pfaff]

"make distcheck" currently fails because doc/ni.texi is not
distributed, which forces the Info documentation to be remade.
But that's not supposed to happen: we shouldn't require it to be
remade if the user doesn't change it, and in fact the distcheck
target enforces that by making the source directory read-only.

The patch below fixes it.  The important part is moving ni.texi
from nodist_doc_pspp_TEXINFOS to doc_pspp_TEXINFOS.  The deletion
of "am__TEXINFO_TEX_DIR=./doc" is unnecessary to fix the problem,
but I couldn't figure out what it was actually doing and it's not
in the change log or the CVS log.

OK to check in?
