freerdp2-dev claims to be Multi-Arch: same but is broken

[Francois Gouget]

Trying to install freerdp2-dev:amd64 and freerdp2-dev:i386 results in the following error:

# apt-get install freerdp2-dev:amd64 freerdp2-dev:i386

Note that freerdp2-dev is no longer marked Multi-Arch: same so this bug should be updated...
