    bitbake: command.py: multiconfig support for findBestProvider
    
    In a multiconfig environment, a tinfoil call such as
    
        tinfoil.parse_recipe("multiconfig:arduino-101-sss:gcc")
    
    can fail with an error such as:
    
      File "/data/master/poky/bitbake/lib/bb/tinfoil.py", line 373, in get_recipe_file
        raise bb.providers.NoProvider('Unable to find any recipe file matching "%s"' % pn)
    bb.providers.NoProvider: Unable to find any recipe file matching "multiconfig:arduino-101-sss:gcc"
    
    The culprit is findBestProvider, which does not handle multiconfig.
    This patch fixes the error and in the case mentioned above the tinfoil call returns:
    
      "multiconfig:arduino-101-sss:/data/master/poky/meta/recipes-devtools/gcc/gcc_6.3.bb"
    
    [YOCTO#11210]
