SQLite lets you put line breaks inside string literals, like this:

If you don't like this syntax, you can pass the string as a BLOB: X'0D' for \r or X'0A' for \n (assuming the default UTF-8 encoding).

Edit: Since this answer was originally written, SQLite has added a CHAR function. So you can now write CHAR(13) for \r or CHAR(10) for \n, which will work whether your database is encoded in UTF-8 or UTF-16.
