[PATCH 08/20] target/riscv: move 'host' CPU declaration to kvm.c

[Daniel Henrique Barboza <dbarboza@ventanamicro.com>]

This CPU only exists if we're compiling with KVM so move it to the kvm
specific file. While we're at it, change its class_init() to enable the
user_extensions_flag class property, sparing us from having to execute
riscv_cpu_add_user_properties() by hand and letting the post_init() hook
do the work.
