(maint) Debian packages install puppetmaster on master nodes

The 01_Install.rb packages/pre-suite script was mistakenly skipping the
puppetmaster install.  Thus the /etc/init.d/puppetmaster script was not
in place.  This change ensures installing puppetmaster package on debian
master nodes.
(maint) Correct ssldir for pre-suite ValidateSignCert

The packages/pre-suite/04_ValidateSignCert.rb setup step was using the
puppetpath host setting to determine ssl dir.  But this does not match
the ssl dir used by installed packages.  This corrects to obtain ssldir
setting from puppet via --configprint.
