NevesHenryandClaude Opus 5.5 faf983ae01 fix(libkernel): give Linux guest threads the stack size they request ...

scePthreadCreate on Linux started guest threads with std::thread, so every
thread got the host default stack (RLIMIT_STACK, usually 8 MiB) whatever the
title asked for. A thread that asks for more than that and uses it crashes
with SIGSEGV. Once the thread ran, scePthreadAttrGet also reported the host
size instead of the requested one.

Create the thread with pthread_create and a stack of the requested size plus
what glibc keeps at its top (static TLS, the thread control block and the
start_thread frame). That reserve is measured once with a probe thread.
The thread reports [top - reserve - size, top - reserve) as its stack, as
Windows reports [top - size, top), and the creator waits until the range is
set, as on Windows.
