[Rd] help.start() fails (PR#935)

[wb@vestein.arb-phys.uni-dortmund.de]

On my system help.start() failed with "could not write .R/doc/html/packages.html" 
or equivalent. This due to /usr/local/lib/R/doc/html/packages-head.html 
having protection -r--r--r--. After inserting 'chmod u+w ${PKGLIST}'
after 'cp ${R_HOME}/doc/html/packages-head.html ${PKGLIST}'in
/usr/local/lib/R/bin/help.links, it works.
