scheibelp f27f20e5b3 replace dash with underscore in os name/version (#7381) ...

Fixes #7356

In some cases OperatingSystem (e.g. LinuxDistro) was getting
instantiated with a version that contains dashes. This breaks because
the concretizer later converts this value to a string and re-parses
it, and the '-' character is used to separate architecture components.
This adds a guard in the initializer to convert '-' to '_'.
