[PATCH v2] hash: update obsolete reference to SHA1_HEADER

From: brian m. carlson <sandals@crustytoothpaste.net>

Message-ID: <20180208024858.872624-1-sandals@crustytoothpaste.net>
In-Reply-To: <xmqqinbfcgzo.fsf@gitster-ct.c.googlers.com>

We moved away from SHA1_HEADER to a preprocessor if chain, but didn't update the comment discussing the platform defines. Update this comment so it reflects the current state of our codebase.
