Wildcards in suite paths are not supported

[Tattoo]

If you provide suite paths to rflint with wildcards, they do not work on Windows.

In POSIX, I guess shell does the wildcard expansion for you, but this is not the case in Windows where neither cmd or powershell will do that for you.

Therefore, on Windows I cannot write:

> rflint -A my_args.robot tests/prefix_*.robot
