Increase max inotify instance

Because of the limit to the amount of inotify fd instance (i.e = 128),
total instances of application execution might be limited. Some _bad_
application, moreover, could use a lot of inotify fd instances
abnormally using eglibc API.

In order to prevent this situation, this work sets the max inotify fd
instance to 1024 as defult value.
