[PATCH v4] selftests/move_mount_set_group:Make tests build with old libc

[PATCH v4] selftests/move_mount_set_group:Make tests build with old libc

[Hu Yadi]

From: "Hu.Yadi" <hu.yadi@h3c.com>

Replace SYS_<syscall> with __NR_<syscall>.  Using the __NR_<syscall>
notation, provided by UAPI, is useful to build tests on systems without
the SYS_<syscall> definitions.

Replace SYS_move_mount with __NR_move_mount
