Avoid truncating read name

[PeteHaitch]

Issue: Read names are truncated by trimadap-mt when the read name contains whitespace
Fix: Use KS_SEP_LINE rather than KS_SEP_SPACE

I hope this is correct way to fix this issue.

Example data

$ fastq-dump -X 1 --readids -Z SRR891268
Read 1 spots for SRR891268
Written 1 spots for SRR891268
