[PATCH] recipe_sanity: Drop rename overwrite detection

[Richard Purdie <richard.purdie@linuxfoundation.org>]

Bitbake itself checks for probelmatic renames now during key expansion so this
check shouldn't be needed anymore (it dates from pre 2011).

(https://git.openembedded.org/bitbake/tree/lib/bb/data.py#n96 in expandKeys())
