onedrive: default onedrive personal to QuickXorHash

Before this change the hash used for Onedrive Personal was SHA1. From
July 2023 Microsoft is phasing out SHA1 hashes in favour of
QuickXorHash in Onedrive Personal. Onedrive Business and Sharepoint
remain using QuickXorHash as before.

This choice can be changed using the --onedrive-hash-type flag (and
config option) so that SHA1 can be selected while it is still
available in the transition period.
