Change split from bytes to lines

[Not-C-Developer]

Hi. Change this. from split -b100M rdns.rev.lowercase.txt fileChunk to split -l2000000 rdns.rev.lowercase.txt fileChunk in scripts/fdns_a.sh and scripts/rdns.sh because lose some records when sorting.

Yes true, it has data loss. it fixed my issue too.

From split's man page: -C, --line-bytes=SIZE put at most SIZE bytes of records per output file

Seems like that would be the best option to use to give you a desired file chunk size without risking data loss.
