As we'll address in subsequent commits the "DC_SHA1=YesPlease" is not
on by default on OSX, instead we use Apple Common Crypto's SHA-1
implementation.
In 6beb2688d3 (fsmonitor: relocate socket file if .git directory is
remote, 2022-10-04) the build was broken with "DC_SHA1=YesPlease" (and
probably other non-"APPLE_COMMON_CRYPTO" SHA-1 backends).
So let's extract the fix for this from [1] to get the build working
again with "DC_SHA1=YesPlease". In addition to the fix in [1] we also
need to replace "SHA_DIGEST_LENGTH" with "GIT_MAX_RAWSZ".
