target/i386: Restrict 'qapi-commands-machine.h' to system emulation

Since commit a0e61807a3 ("qapi: Remove QMP events and commands from
user-mode builds") we don't generate the "qapi-commands-machine.h"
header in a user-emulation-only build.

Guard qmp_query_cpu_definitions() within CONFIG_USER_ONLY; move
x86_cpu_class_check_missing_features() closer since it is only used
by this QMP command handler.
