package/nodejs: use ninja for build

Not only is ninja much faster, it also avoids the following build
failure:
make[3]: printf: Argument list too long

This failure happens when the output directory is about 6 levels deep.
It's due to the make generator of gyp that uses some crazy shell
processing for splitting up paths on /. The ninja generator does no such
thing.

While we're at it, remove redundant parenthesis in
HOST_NODEJS_CONFIGURE_CMDS.
