Make rnp work on OpenBSD (WIP)

[ronaldtse]

This is WIP, there are a few issues in the build scripts:

TAR

tar ... --strip 1 in ci/install.sh does not work on OpenBSD

GnuPG

Compilation of libassuan gives this error.

In fact, OpenBSD (and macOS brew) comes with GnuPG 2.1 and we probably don't need to re-compile things?

@dewyatt could we skip the build of GnuPG if the system's version is already 2.1+?

Looks like EPROTO could be replaced with EIO on *BSD:
