Windows doesn't allow : in filenames.

Commit 6fdece9a added files with a : in
their names. This broke git operations on Windows as git is not able to
create those files on clone or pull.

Replace : with - in the offending filenames and adapt the test case.
As the tested Linux specific code expects the files to exist with : in
their path use symlinks to provide the name that way.

This creates the basic unit tests for the scsi utils.
