This patch renames a few functions in util/biosdisk.c.  Currently, by looking
at get_drive(), find_drive(), get_os_disk() function names it is very difficult
to figure out what's going on.  They're even misleading in fact.  I propose
the more descriptive names find_grub_drive(), find_system_device() and
convert_system_partition_to_system_disk().
