hooks--pre-push.sample: use hash-agnostic zero OID
The pre-push sample hook has the zero OID hardcoded as 40 zeros. However, with the introduction of SHA-256 support, this assumption no longer holds true. Replace the hardcoded $z40 with a call to git hash-object --stdin </dev/null | tr '[0-9a-f]' '0' so the sample hook becomes hash-agnostic.
