libxl: include sys/ioctl.h

This is a requirement for the code in libxl_remus_disk_drbd.c that uses the
ioctl syscall. Fixes the following error when building on FreeBSD:

libxl_remus_disk_drbd.c: In function 'drbd_postsuspend':
libxl_remus_disk_drbd.c:197:9: error: implicit declaration of function 'ioctl' [-Werror=implicit-function-declaration]
