bitbake: bitbake-getvar: Catch NoProvider exception

When the recipe provided by (-r, --recipe) is not found
tinfoil raises an exception that is not catched for
readability, example:

Traceback (most recent call last):
  File "/.../poky/bitbake/bin/bitbake-getvar", line 45, in <module>
    d = tinfoil.parse_recipe(args.recipe)
        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/.../poky/bitbake/lib/bb/tinfoil.py", line 633, in parse_recipe
    fn = self.get_recipe_file(pn)
         ^^^^^^^^^^^^^^^^^^^^^^^^
  File "/.../poky/bitbake/lib/bb/tinfoil.py", line 550, 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 "aaa"
