[Libosinfo] [PATCH osinfo-db] tests: Simplify 'make check'

[Cole Robinson]

Strip out everything except: python3 -m pytest --log-level=info

* Per test log files are dropped entirely. This was just capturing
  the same test output we get from stdout and saving it. IMO just
  depending on stdout is good enough
* pytest  will scoop up all the test files and run them in one batch.
* 'make' will print the command before running, so any users will see
  how to invoke the tests manually if they want to add pytest options.
* Missing python3 or pytest module will generate an error, no need to
  report a custom message to the user
