libmount; fix and improve read+poll mountinfo

* fix read() buffer size (stupid bug...)

* split read() EINTR and poll() based attempts

* use 100 attempts

* wait 10000 usec between attempts, but first 10 attempts are without
  this delay. It makes the function usable for usual use-cases as well
  as on very busy systems (successfully tested with 300 concurrent
  mount/umount processes)
