Tino Reichardt 48cf170d5a Add PPC cpu feature tests for FreeBSD and Linux 
Add needed cpu feature tests for powerpc architecture.

Overview:
zfs_altivec_available() - needed by RAID-Z
zfs_vsx_available()     - needed by BLAKE3
zfs_isa207_available()  - needed by SHA2

Part 1 - Userspace
- use getauxval() for Linux and elf_aux_info() for FreeBSD
- direct including <sys/auxv.h> fails with double definitions
- so we self define the needed functions and definitions

Part 2 - Kernel space FreeBSD
- use exported cpu_features of <powerpc/cpu.h>

Part 3 - Kernel space Linux
- use cpu_has_feature() function of <asm/cpufeature.h>
