Avoid error for incorrect root directory

Forwarded: not-needed

Avoid error for incorrect root directory. Test/build.js expects
"bluebird". When building in Debian, the root directory
changes (e.g. node-bluebird-3.4.6). Although this should not matter for
Debian (the check is probably just in case a developer tries to
run the tests outside of the root directory), this patch checks that
at least the first 13 characters of the root directory contain
"node-bluebird".
