Fix syntax error in pattern substitution
First round of SUSE specific additions to install-crowbar-native.sh

* On SUSE based installs we don't (yet) rely on the install media copied to the
  harddisk (install can also happen from a network source
* All gems are packaged as RPMs
* Different name of the rsyslog init script
* discovery image is packaged in an RPM
* install Cloud_Admin pattern
* No need for chef init scripts (chef is setup from install actions)
barclamp_install: Only upload chef components if knife is configured

This is to avoid barclamp_install.rb erroring out when installing the crowbar
barclamp before the chef barclamp's install actions set up chef.
