syscall: rename module name to syscall_steal

In Debian, the name syscall conflicts with this patch: in debian kernel source tree: debian/patches/features/x86/x86-make-x32-syscall-support-conditional.patch mailing list url: https://lore.kernel.org/lkml/[email protected]/T/#u which introduces a parameter named syscall.x32. So change our name.
