tools: ceph-detect-init: support SLED

SUSE Linux Enterprise (SLE) comes in two variants: SLES (for servers) and SLED
(for desktops). This commit adds support for the desktop variant as well as
adding test cases for SLE 15.

This commit is not cherry-picked because ceph-detect-init has been dropped in
master.
