Cleanup inotify syscalls decoding

* linux/inotify.h: New file.
* file.c (inotify_modes, inotify_init_flags, sys_inotify_add_watch,
sys_inotify_rm_watch, sys_inotify_init1): Move...
* inotify.c: ... here.
(inotify_modes): Rename to inotify_flags, convert to XLAT form.
(inotify_init_flags): Convert to XLAT form.
* Makefile.am (strace_SOURCES): Add inotify.c.
(EXTRA_DIST): Add linux/inotify.h.
