Dashes in script file names make Scala Native complain during linking, with Scala 2 #1266

Not sure if it's a Scala CLI bug, or more of a Scala Native bug.

Version(s) 0.1.11

Describe the bug

Having a - in the name of an .sc file, such as test-native.sc, makes Scala Native complain that the main class is missing, when using Scala 2 (things seem to work fine with Scala 3).

To Reproduce

$ cat test-native.sc
println("Hello")

$ scala-cli --native test-native.sc

The problem was happening on the SN side. This issue would be fixed in Scala Native 0.4.8 https://github.com/scala-native/scala-native/pull/2955
