PTRACE_SET_SYSCALL_INFO is a generic ptrace API that complements
PTRACE_GET_SYSCALL_INFO by letting the ptracer modify details of
system calls the tracee is blocked in.
This API allows ptracers to obtain and modify system call details in a
straightforward and architecture-agnostic way, providing a
This function is going to be needed on all HAVE_ARCH_TRACEHOOK
architectures to implement PTRACE_SET_SYSCALL_INFO API.
This partially reverts commit 7962c2eddbfe ("arch: remove unused
function syscall_set_arguments()") by reusing some of old
syscall_set_arguments() implementations.

In the interest of keeping the patch reasonably-sized this doesn't
refactor the tests into proper parameterized tests - it's all one big
test case.

This is one of just 3 remaining "Test Module" kselftests (the others
being bitmap and scanf), the rest having been converted to KUnit.
I tested this using:
$ tools/testing/kunit/kunit.py run --arch arm64 --make_options LLVM=1 printf
I have also sent out a series converting scanf[0].

Move all tests into `printf_test_cases`. This gives us nicer output in
the event of a failure.
Combine `plain_format` and `plain_hash` into `hash_pointer` since
they're testing the same scenario.
