Fix printf format character for 32-bit machines
Fix printf format character for 32-bit machines

On my 32-bit machine, I got this error while compiling:

  root.c: In function 'try_read_inotify':
  root.c:1809:9: error: format '%lu' expects argument of type 'long
    unsigned int', but argument 4 has type 'unsigned int'
    [-Werror=format]

Changing the length modifier from 'l' to 'z' fixed this. C99 defines
the 'z' length modifier as the platform-independent modifier for
size_t arguments.
