tests: Fix some issue with test for swtpm_setup --profile

Fix the following issues:
- use a regular expression instead of hard coded '4' to match
  StateFormatLevel number that will change in the future
- get all available profiles from running tpm rather than only the active
  profile -> use --info 0x40
- only compare with regular experssion if it is non-empty because
  this otherwise fails on Cygwin
