go/ssa/interp: add internal/syscall/unix.syscall_fcntl to fix tests

Browse Source 
CL 100077 added the syscall_fcntl function in the internal/syscall/unix
package to refer to syscall.fcntl outside of the syscall package in a
unified way.

Add a replacement that simulates a successful fcntl call to fix the
interp tests.
