build/ops: rpm: make sudo a build dependency

ede36df3253bd67bfe206abc0446f1f156feae64 added sudo as a runtime dependency,
but that commit also causes OBS builds to fail with:

[10666s] ... checking filelist
[10667s] ceph-osd-14.0.0-lp150.1332.1.x86_64.rpm: directories not owned by a package:
[10667s]  - /etc/sudoers.d

Since the "sudo" package is a runtime dependency of ceph-osd, it is guaranteed
to be installed on the target system and there is no reason for ceph-osd to own
this directory.

Having sudo as a build dependency makes OBS happy, and does no harm.

Follow-on fix for https://github.com/ceph/ceph/pull/22745
