Mark lua setjmp/longjmp for powerpc weak
Linux already defines setjmp/longjmp for powerpc, which leads to
duplicate symbols in a statically linked build.

Add longjmp support for Thumb-2
When a Thumb-2 kernel is being used, then longjmp must be implemented
using the Thumb-2 instruction set in module/lua/setjmp/setjmp_arm.S.

Porting Notes:
* The CLI long option arguments for '-t' and '-m' don't parse on linux
* Switched from kmem_alloc to vmem_alloc in zcp_lua_alloc
* Lua implementation is built as its own module (zlua.ko)
* Lua headers consumed directly by zfs code moved to 'include/sys/lua/'
* There is no native setjmp/longjump available in stock Linux kernel.
  Brought over implementations from illumos and FreeBSD
* The get_temporary_prop() was adapted due to VFS platform differences
* Use of inline functions in lua parser to reduce stack usage per C call
* Skip some ZFS Test Suite ZCP tests on sparc64 to avoid stack overflow
