Subject: [PATCH] Tolerate when endian.h is symlink to sys/endian.h

Since 5a60b36fe9b45b68244596d93db2b922d53e7b5c varnish drop support of
sys/endian.h and they had a bit different API one or two leading `_`.

Some system may have symlink from endian.h to sys/endian.h, for example
OpenBSD. On such system build fails due to wrong SHA256 hash.
