[Luke Daley]

• Use the system implementation of the actual variant of the system function that was requested.

e.g. If the client app is actually linking against ‘_write$NOCANCEL$UNIX2003’, we now call that implementation after our custom stuff. Previously we just called ‘_write’ regardless.

Also provided system_* functions for functions that we overwrite so we contain the logic of getting to the system implementation in one place.
