build: prefer '$(top_srcdir)/doc' over '$(srcdir)' in doc Makefile

Browse Source 
This is just a preparatory refactoring that will become useful in
a future change (in which the doc/Makefile.am makefile will be merged
with the top-level one).

* doc/Makefile.am (doc_srcdir): New, define to '$(top_srcdir)/doc'.
Use it throughout instead of "bare" '$(srcdir)'.
