d/control: fix lua dependencies for librgw2

See inner commit message for details.

Semi-related: ceph-common, which pulls in python3-rgw in the first
place, should really split up in a handful of packages, which would
avoid this issue for us too, as we do not require RGW tooling by
default.

+Subject: [PATCH] d/control: fix lua dependencies for librgw2
+
+One can attach lua scripts as sort of hooks to implement dynamic
+checks or transformations of RGW requests since Ceph Pacific. A lua
+library is now required for base support and optionally one can use
+the luarocks deployment and management system for Lua modules to use
+more advanced scripts/modules.
+
+With commit 46500cace6c ("rgw/test/lua: add lua integration tests
+suite") the dependency relations where cleaned up, as the respective
+entries where missing from debian/control.
+
+But that commit is pulling in much more than required due to adding
+the devel package `liblua5.3-dev` instead of the library-only
+`liblua5.3-0` one, and having `luarocks` as hard dependency compared
+to an optional Suggests. Fixing that avoids pulling in a whole
+build/compiler/autotools/... stack just when one wants to use librgw2
+or python3-rgw for simple RGW requests.
+
+This is a result of some discussion on the original PR [0].
