Honour the commandline -semihosting-config userspace=on option,
instead of always permitting userspace semihosting calls in system

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.

MIPS semihosting is not implemented for linux-user builds.
