This update allows to remove unsupported from generic archs in the package INFO file.

@publicarray this is probably useful for jellyfin package, since all dotnet dependent packages do not support all ARMv7 archs.

[hgy59]

Considering #5283 armadaxp might be supported.

@hgy59 Looks good to me.

Since .net 6.0 raised the required system libs versions, you can basically drop all of DSM 6 support and comcerto, unfortunately. AFAIK, only DSM7.0 and above contains the libraries necessary. (@ta264 https://discord.com/channels/732558169863225384/905064261984845836/1004134443755241582)

Thanks @hgy59, for compiling the unsupported arches, unfortunately I think this information is only valid for .NET 5.x. In.NET 6.x support is worse 😢
