RFE: On Fedora, have the RPM 'provide' traditional /sbin/zpool and /sbin/zfs commands

[siebenmann]

After #18373 was merged, the current Fedora RPMs naturally don't provide /sbin/zpool and /sbin/zfs (in the RPM sense), although those paths remain valid and working. Unfortunately, there are at least some other RPMs out there in the field that 'Require' these things (the one I know of is the libvirt-daemon-driver-storage-zfs from @virtmaint-sig/virt-preview COPR repository). It would be handy for this if the Fedora RPMs would manually 'Provide' these paths so that such packages still worked.

(I believe this would also make it so that the OpenZFS RPMs explicitly conflicted with any other RPM, like zfs-fuse, that Provided those paths as well.)

It seems like other packages could have a similar dependency problem. I'm a little surprised this potential snag isn't mentioned in the https://fedoraproject.org/wiki/Changes/Unify_bin_and_sbin guidance. Regardless, adding the additional "Provides" lines for the alternate /sbin/ path strikes me a pretty reasonable way to handle it. @Lalufu what do you think?

I think that would be reasonable to carry for a while.
