[PATCH] perf-test: update corpus signature

[David Bremner <david@tethera.net>]

In the decade (!) since this corpus was last updated, the keyserver
network is essentially dead, and I have migrated gpg keys. Bump the
version number as a clean way of switching signatures. Also update the
instructions to suggest using "--locate-external-key" to download the
public key. By default this uses WKD, which is now supported for my
UID.

 First, you need to get the corpus.  If you don't already have the gpg
 key for David Bremner, run
 
-   % gpg --search 'david@tethera.net'
+   % gpg --locate-external-key 'david@tethera.net'
 
 This should get you a key with fingerprint
