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.
