oeqa/core/loader.py: support the 'auto' keyword

In previous OEQA, having 'auto' in TEST_SUITES results in executing
as many test cases as possible.

This behaviour is broken for now. From the codes in core/loader.py,
I can see that it tries to use another keyword 'all'. But in fact,
it does not work.

I've checked the current manual. The manual says using 'auto'.
Below is the current information in manual.

  """
  Alternatively, you can provide the "auto" option to have all applicable
  tests run against the image.

  TEST_SUITES_append = " auto"
  """

So we should restore this behaviour. This patch does so.

Also, output warning message is some module is named as 'auto', as this
is a reserved keyword.
