If SYS_statmount/SYS_listmount is not provided by the libc,
util-linux will fall back to __NR_statmount/__NR_listmount from the
kernel UAPI headers.
However it is not guaranteed that these symbols are actually visible in
mount-api-utils.

Include linux/unistd.h which provides syscall numbers.
While this header is specific to Linux, the code is already using
linux/mount.h.
