Isolation: Remove the syscall(SYS_getpid) wrapper.
When using SYS_clone we used the getpid kernel system call directly via syscall(SYS_getpid) to avoid issues with cached pids. However since we are now only using fork(2) (+ unshare(2) for namespaces) we no longer need to call the kernel getpid directly as the fork(2) will ensure the cached pid is invalidated.
