rpm: resolve a host contamination issue for mono packaging

This is perhaps not the most elegant patch but it be dropped
once rpm is updated to the soon-to-be-released version 4.15
where upstream has removed mono dependency resolution altogether.

+Subject: [PATCH] mono-find-provides/requires: do not use monodis from the host
+
+There was a host contamination issue here: if monodis was installed
+on the host, do_package would use that to resolve dependencies
+of mono libraries (and often fail in that). Without monodis,
+no dependencies are resolved, which is seemingly how things
+are supposed to work.
