append random string to generated names

- generated names for taskruns and build steps get a random suffix of five alphanumerics. The string is guaranteed to not exceed the length of a standard Kubernetes name (63 characters) - updated tests using fixed seed for the name generation - remove rand string func from test folder - use new rand string already used for generated names
