Subject: Avoid using 'head' in generating groff doc date

It may not be available in certain cross build cases.

Note that this is a slight change in functionality, in that now only the
first line of the source ChangeLog file is processed. This is acceptable
as groff will be retired and we won't encounter a possibly-different
ChangeLog format.
