Update kernel-features.h files for Linux 5.1.
Linux 5.1 adds missing syscalls to the syscall table for many Linux
kernel architectures. This patch updates the kernel-features.h
headers accordingly. __ASSUME_DIRECT_SYSVIPC_SYSCALLS is not updated
because of the differences between new and old syscalls described in
<https://sourceware.org/ml/libc-alpha/2019-05/msg00235.html>. The
statfs64 structure used by alpha matches what the new kernel syscalls
use.
Tested with build-many-glibcs.py.
* sysdeps/unix/sysv/linux/alpha/kernel-features.h
(__ASSUME_STATFS64): Only undefine if [__LINUX_KERNEL_VERSION <
0x050100].
* sysdeps/unix/sysv/linux/ia64/kernel-features.h (__ASSUME_STATX):
Likewise.
* sysdeps/unix/sysv/linux/sh/kernel-features.h
(__ASSUME_STATX): Likewise.
