nasm-t: do not strip newlines from output

Currently we strip newlines from files on read and write
procedures for better diff output, but as being pointed
by hpa@ this makes quite inconvenient to work with tests
in a manual mode.

Thus lets left outputs as is. We have to update all tests
with template outputs since by default output streams are
ending with newline.
