PR Summary

SC is a default alias for Set-Content, however on Windows there is a sc.exe command for managing NT Services.
If a user executes sc start service1 in a PowerShell script, what happens is that a file called start is created containing service1 as the content with no error so the user/script may think the service got started.
In addition, there is also a sc command on Linux, although it's not installed by default.
If the customer feedback is that we should not have removed this, it'll be easier to add it back in 6.1.0 than to ever try to remove it after 6.0.0.

Fix is to remove sc alias from InitialSessionState and corresponding test case.
This was discussed with some members of @PowerShell/powershell-committee whom agreed to the removal.
