Bug#1036916: RM: librust-wayland-commons-dev -- ROM; Obsolete, blocks other packages from migrating

[Jeremy Bícha]

Control: tags -1 +moreinfo

This package isn't ready for removal until the rust-wayland-* packages
that Build-Depend on it are uploaded to Unstable without that
dependency. When that happens, please remove the moreinfo tag.

Thank you,
Jeremy Bícha
