use sys/inotify.h
Some time ago glibc did not yet have inotify support, which forced several applications (including inotail) to ship their own copy of the required headers. Especially considering that this also requires updating the syscall numbers each time a new architecture wants to get supported it's the best to instead switch to #include <sys/inotify.h> now.
