SCI32: Hide warning about CD-ROM speed setting in kGetSierraProfileInt

In the DOS interpreters, this function is a no-op. Lighthouse calls
it regardless of platform, so dummy it out for non-Windows
platforms. This is not known to address any particular issue, and
is really just to eliminate the warning about an unknown
configuration setting when starting Lighthouse in a manner that is
compatible with the original interpreter.
