milescovielloandClaude Opus 5.5 d7c83db2a5 feat(libkernel): read and set the GS base through sysarch ...

sysarch's AMD64_GET_FSBASE, AMD64_GET_GSBASE and AMD64_SET_GSBASE now
follow FreeBSD 11's amd64 sysarch on Linux x86-64 through arch_prctl: the
GS base is the calling thread's, a base at or above VM_MAXUSER_ADDRESS
returns EINVAL and a null argument EFAULT. AMD64_SET_FSBASE, whose base
guest and host code share for their TLS, other operations and other hosts
still throw. Wine sets its TEB this way.
