Fix update_web_docs_svn for Ada manual

[Joseph S. Myers]

A recent Ada change broke the nightly update_web_docs_svn run because the 
generated gnat_ugn_unw.texi was including a file projects.texi from the 
source directory and that script wasn't using appropriate -I options for 
this file to be found.  I've applied this patch to fix this.
