Diskmanage: refactor and rename get_parttype_info

Browse Source 
in preparation to also query the file system type from lsblk. Note that the
result now also includes devices without a parttype, so a definedness check in
get_devices_by_partuuid is needed. This will be useful when the whole device
contains a filesystem.
