Fixes a segfault (divide by zero in create_unique_file()).
Don't pass in a zero size into create_unique_file(), since
this function attempts to create and populate a file the
asked size (it also causes a division by zero error when
the size is zero).
Test: Run puncture_fs several times to cover case where
the random number generator returns value which would have
caused size to be 0 (tested with debug printf to catch
the case where we regenerated the random number).

puncture_fs: A new utility that is used with fs benchmarking tools.
The tools fills up the filesystem completely then removes a set of files
of predefined size to free up some predefined non-contiguous free space.
It is used with benchmarking tools like fio to collect metrics on a used filesystem with sparse free space.
