[zinc] Add PowerPC accelerated poly1305 from openssl/cryptogramssl/ppc
Unfortunately I am not seeing a speed up with this patch,
but it does decrease CPU usage.
Only (currently) runs on the outbound path, as the in-bound path is in
an interrupt, but that can be fixed in Linux.
v2: - Do not include the FPU version, as +10% performance on POWER8
(admittedly better on really old CPUs, like old world macs) is not
worth it, especially when there is a fast VSX version available.
- Honor CONFIG_VSX.
