part-get-bootable: Fix when partitions are missing or unordered (RHBZ#602997).

Browse Source 
The original fix for this in
commit 511c82df46 was not complete, in
that it did not fix the case of the old (pre '-m' option) parted.
This doesn't matter for Fedora, but it matters for RHEL 5 which has
this ancient parted.
