recipetool: create: don't create extra files directory unconditionally

The extra directory next to the recipe should only be created if there
are files to put into it; currently only the npm plugin does this. I
didn't notice the issue earlier because the test was actually able to
succeed under these circumstances if the recipe file came first in the
directory listing, which was a fault in my original oe-selftest test;
apparently on some YP autobuilder machines the order came out reversed.

With this change we can put the oe-selftest test that highlighted the
issue back to the way it was, with an extra check to reinforce that only
a single file should be created.
