wireguard: remove misspelled debugging line

There are no other "echo" debug lines in this file, and it seems
clear that this one was accidentally left as a debugging line,
since it misspelled "dependency". So, we just remove this line.

We don't bump the package version, though, because this is
pretty inconsequential.
