I was thinking we would need to keep the existing sctp_sha1.h name, so that we
could limit the amount of changes to calling code (which already includes
sctp_sha1.h). 

Inside sctp_sha1.h, we would have #ifdefs to decide which implementation to
actually use.

I see. Since we ruled out the existing sha1 implementation and
sctp_os_userspace.h already had place for openssl, so i removed sctp_sha1.h
implementation from overrides folder.

I know this is ugly, but sctp_sha1.h included from sctp_os_userspace.h and
sctp_auth.h both are already in overrides folder, so this didn't cause any
issues.

Let me try to do what you are suggesting here.
