Fix inotify configure test.

AC_CHECK_FUNCS executes "action-if-found" or "action-if-not-found" for
each function in the list.  If a system has some but not all of the
functions, both will end up being executed.

This caused a build failure on an older system with exactly that
situation.

Change to only define USE_INOTIFY if all functions exist.
