sha1dc: update from upstream

Update sha1dc from the latest version by the upstream
maintainer[1]. See 07a20f569b ("Makefile: fix unaligned loads in
sha1dc with UBSan", 2019-03-12) for the last update.

This fixes an issue where HP-UX IA64 was wrongly detected as a
Little-endian instead of a Big-endian system, see [2] and [3].
