xtables-restore: Allow lines without trailing newline character
Old code in add_param_to_argv() assumed the input line would always end
with a newline character. Without it, the last word of input wasn't
recognized. Fix this by adding a final check for param.len (indicating
leftover data in buffer).
In line parsing code itself, only COMMIT line check required presence of
trailing newline. The replaced conditional is not 100% accurate as it
allows for characters after newline to be present, but since fgets() is
used this shouldn't happen anyway.
