ycp is dead so ycpdoc is also dead

It is already obsoleted by VMs and new yast should run from checkout
remove findlogid as logs no longer have ids
remove generator of source code header
Removed ycpdoc/doc also from Makefile.am

useless. The actually used thing is in
devtools/skeletons/config/doc/autodocs/Makefile.am
removed a useless file
remove perl-XML-Writer dependency: was used for ycpdoc
