Do not trick info/dir’s timestamp

* Makefile.in (${srcdir}/info/dir): When making this file, do not
do anything special about its timestamp.  Previously this rule
used move-if-change, which meant that this file’s timestamp could
end up being older than the files it depends on, and this caused
‘make --question info’ to fail, which caused ‘make-dist’ to fail
now that ‘make-dist’ invokes ‘make --question info’.
