Generalize dotnet-runtime-deps Deb/RPM package dependencies (dotnet/core-setup#6070)

* Expand runtime-deps package applicability

On RPM package distros, depend on the libicu capability that a libicu## package provides.

On Debian package distros, use "or" dependencies that list all known versions of libicu and libssl.

This removes the need for some distro-specific packages.

* Collapse identical Deb packages into one
