datatop: fix file line count helper function always returns 0 lines

When porting the snapshot, a change was made to
dtop_get_file_line_amount() to initialize rc to -1. glibc defines
EoF as -1 thus causing the for loop to never get executed. A line count
of 0 was getting returnd thus causing ~1500 data points to not get
polled. Instead, initialize rc to 0.
