[Buildroot] [PATCH] support/dependencies/dependencies.sh: simplify an error message

[Markus Mayer]

There is no need to break the "\n" sequence using "%sn". We can just
escape it. Note: the escaping backslash needs to be escaped too,
because the shell will process the string before printf gets to see it.

Maybe we should have used single quotes here to get rid of one layer of
quoting.

Committed, thanks.
