[oe] [meta-python][PATCH] python-attrs: Adjust the RDEPENDS to include crypt rather than cryptography

[jan vermaete]

I'm afraid this patch just revert the file to the previous state.
As far as I can see, there is no need at all to have something of
crypto nor crypotgraphy needed for this python package.
