[scarthgap][PATCH] bitbake: bitbake-user-manual-metadata: fix missing option to 'echo' command in example

The original text reads:
| values. For these to have an effect, the value must be passed to some
| utility that interprets escape sequences, such as
| ``printf`` or ``echo -n``.

The '-n' option tells echo to not append a newline to the output.
What's missing here is the '-e' option to "enable interpretation of
backslash escapes".
