grubby-bls: use title field instead of version for zipl default entry 

Most bootloaders use the BootLoaderSpec "title" field to name the entries
in their boot menu. The zipl bootloader used the "version" field instead,
since it was wrongly assumed that the zipl boot menu didn't support names
that contained spaces, which are usually present in a BLS "title" field.

But this is not the case, names with space characters are supported by the
IPL and is just a constraint of the section heading in the zipl.conf file.

To be consistent with all the other bootloaders, zipl now uses the "title"
field to populate the boot menu entries from BLS files. So change grubby
to use the "title" field to set the default entry of the "version" field.
