sys_clone has many flavors in Linux, and amd64 chose
a different one from x86(different arguments order).
Ref kernel/fork.c for more info.

When an interpreter script is opened with O_CLOEXEC and the resulting fd is
passed into execveat, an ENOENT error should occur (the script would otherwise
be inaccessible to the interpreter). This matches the actual behavior of
Linux's execveat.

This change simplifies the function signatures of functions related to loading
executables, such as LoadTaskImage, Load, loadBinary.
PiperOrigin-RevId: 276821187
Adds feature to launch from an open host FD instead of a binary_path.
The FD should point to a valid executable and most likely be statically
compiled. If the executable is not statically compiled, the loader will
search along the interpreter paths, which must be able to be resolved in
the Sandbox's file system or start will fail.

The previous commit adds WNOTHREAD support to waitid, so we may as well
complete the upstream change.
Linux added WCLONE, WALL, WNOTHREAD support to waitid(2) in
91c4e8ea8f05916df0c8a6f383508ac7c9e10dba ("wait: allow sys_waitid() to
accept __WNOTHREAD/__WCLONE/__WALL"). i.e., Linux 4.7.
