target/xtensa: Honour -semihosting-config userspace=on
Honour the commandline -semihosting-config userspace=on option, instead of always permitting userspace semihosting calls in system emulation mode, by passing the correct value to the is_userspace argument of semihosting_enabled(). Note that this is a behaviour change: if the user wants to do semihosting calls from userspace they must now specifically enable them on the command line. xtensa semihosting is not implemented for linux-user builds.
