cmd/go/internal/modfetch/codehost: add support for new fossil info hash prefix

Browse source 
A recent update of the Fossil SCM application changes the line prefix when the fossil info command is used.
Instead of the revision hash starting with "uuid:", it has been changed to "hash:".

Fossil check-in introducing this change: https://fossil-scm.org/home/info/8ad5e4690854a81a

To support both older and new versions of fossil, fossilParseStat will now check for either version of the prefix
when attempting to find the line containing the hash of the desired revision.

Fixes https://github.com/golang/go/issues/42323
