the substvar of `${shlibs:Depends}` is set by dh_shlibdeps, which
inspects the ELF images being packaged to figure out the shared
library dependencies for packages. but since f3c3b9183c,
we just override the `override_dh_shlibdeps` target in debian/rules
with no-op. as we take care of the shared library dependencies by
vendoring the runtime dependencies by ourselves using the relocatable
package. so this variable is never set. that's why `dpkg-gencontrol`
complains when processing `debian/control` and trying to materialize
the substvars.
in this change, the occurances of `${shlibs:Depends}` are removed
to silence the warnings from `dpkg-gencontrol`.
