oeqa: loader.py: show warning when skipping selected module and abort if all are...

* skipped modules were triggering an ERROR before:

  poky $ oe-selftest -v -r eSDK.oeSDKExtSelfTest.test_install_libraries_headers imagefeatures.ImageFeatures.test_image_gen_debugfs -K -B /OE/build/poky/build-eSDK
  2023-03-13 15:07:53,430 - oe-selftest - ERROR - Not found eSDK.oeSDKExtSelfTest.test_install_libraries_headers in loaded test cases

* but didn't show the reason why it wasn't loaded and more importantly -r
  was ignored when all selected modules were silently skipped

* add a warning when skipping some module and abort if some modules were
  selected, but all ended being skipped:

  poky $ oe-selftest -v -r eSDK.oeSDKExtSelfTest.test_install_libraries_headers -K -B /OE/build/poky/build-eSDK
  2023-03-13 15:11:51,028 - oe-selftest - WARNING - module 'eSDK.oeSDKExtSelfTest.test_install_libraries_headers' was skipped from selected modules, because it doesn't match with module name assumptions: package and module names do not contain upper case characters, whereas class names do
  2023-03-13 15:11:51,028 - oe-selftest - ERROR - All selected modules were skipped, this would trigger selftest with all tests and -r ignored.

* I was hit by this in oe-selftest -r eSDK.oeSDKExtSelfTest.test_install_libraries_headers
  which is skipped due to upper case characters in module name and selftest started to run
  all tests (archiver.Archiver.test_archiver_allows_to_filter_on_recipe_name as first from 529)

  poky $ oe-selftest -v -r eSDK.oeSDKExtSelfTest.test_install_libraries_headers -K -B /OE/build/poky/build-eSDK
  2023-03-13 14:00:52,955 - oe-selftest - DEBUG - Selected tests with -r: ['eSDK.oeSDKExtSelfTest.test_install_libraries_headers']
  2023-03-13 14:00:55,531 - oe-selftest - INFO - Changing cwd to /OE/build/poky/build
  ..
  2023-03-13 14:00:58,128 - oe-selftest - INFO - test_archiver_allows_to_filter_on_recipe_name (archiver.Archiver.test_archiver_allows_to_filter_on_recipe_name)

  I'll rename eSDK to esdk in next commit to avoid this.

* also fix small typo in context I've noticed when debugging this
