selftests/nolibc: introduce QEMU_ARCH_USER

While ppc64le shares the same executable with regular ppc64 the user
variant needs has a dedicated executable.
Introduce a new QEMU_ARCH_USER Makefile variable to accommodate that.

Fixes: 17362f3d0bd3 ("selftests/nolibc: use qemu-system-ppc64 for ppc64le")
