commit 1421ec684a43379b2aa3cfda20b03d38282dc990 upstream. Resctrl test suite accepts command line argument "-t" to specify the unit tests to run in the test list (e.g., -t mbm,mba,cmt,cat) as documented in the help. When calling strtok() to parse the option, the incorrect delimiters argument ":\t" is used. As a result, passing "-t mbm,mba,cmt,cat" throws an invalid option error. Fix this by using delimiters argument "," instead of ":\t" for parsing of unit tests list. At the same time, remove the unnecessary "spaces" between the unit tests in help documentation to prevent confusion.
