Restrict Buster architectures to amd64 for DART

[j-rivero]

We don't have packages for Buster on i386, armhf or arm64. The PR uses restrictions list ([amd64]) to avoid DART dependencies build on these architectures. The PR also modifies the Architecture field in -dartsim- packages to only produce them on amd64.

Tested on Buster/i386:
