Subject: Fix boot-script parsing for openSUSE ppc media

Add an enhancement to deal with configurations in /ppc/bootinfo.txt like
<boot-script>boot &device;:1,\suseboot\yaboot.ibm</boot-script>.
This would evaluate to boot cd:0,1\suseboot\yaboot.ibm which results
in a file not found error (seen on many openSUSE ppc media).

With this patch the above will evaluate to boot cd:0,\suseboot\yaboot.ibm
and yaboot will load.
