logger: use write with \r\n instead of writeln

Browse Source 
The device manager will set tty or pty to raw mode, all the `\n` will
be LF without CR, which makes the output difficult to read.

This commit solves it by using `write` with `\r\n` instead of
`writeln`, which can print CR and LF explicitly.
