Just four new *at variants of the xattr syscalls.
This will also let us use the *at variants for the non-at versions but I
didn't implement that optimization because this is brand new.
This was a funny joke that this was here, but it is fundamentally
incompatible with what we're doing. All those users are running proot

Just remove this from here.
Which requires moving LinuxEmulation to its own independent folder as
well. Since both IRLoader and FEXLoader rely on it.
No functional change, just moves the the code around.
