Make cgo psx_syscall variant crash like runtime.AllThreadsSyscall
When a syscall that yields different return values is called from
the Go psx.Syscall*() API, we want to mirror the behavior of the
native golang runtime.AllThreadsSyscall() function.
The previous inconsistency was pointed out by Lorenz Bauer in:
https://bugzilla.kernel.org/show_bug.cgi?id=215283#c8
[I decided to defer this change until 2.63, and not include this
in the bug-fix for 215283, on the grounds it is a slight
incompatibility in runtime behavior, and wanted to give folk an
opportunity to plan for it. This new behavior enforcement will
crash an unprepared go program.]
