hash: update obsolete reference to SHA1_HEADER

bk2204 · gitster · commit b212c0ca318b · 2018-02-09T09:56:10.000-08:00
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.
