oeqa/utils/decorators: fix missing keyword arguments on decorators
We need to handle keyword arguments here or sending a keyword argument
to a decorated function that accepts keyword arguments will trigger an
error. (This showed up when testcase decorators were added to the
recipetool.RecipetoolTests.test_recipetool_appendsrcfiles_basic_subdir
test).
