src: install npm@3 with npm@2

Restore the ability to do one-shot upgrades from the versions of npm
bundled with Node 0.8 to npm@3, which simplifies using Travis with old
Node and new npm, for compatibility testing purposes. Older versions of
npm repack packages on install, which works poorly with the way npm@3
handles bundledDependencies with flat trees.

Fixes: #9668

+unique-slug
+===========
+
+Generate a unique character string suitible for use in files and URLs.
+
+```
+var uniqueSlug = require('unique-slug')
+
+var randomSlug = uniqueSlug()
+var fileSlug = uniqueSlug('/etc/passwd')
+```
+
+### uniqueSlug(*str*) → String (32 chars)
+
+If *str* is passed in then the return value will be its md5 digest in
+hex.
+
+If *str* is not passed in, it will be 16 bytes coverted into 32 hex
+characters, generated by `crypto.pseudoRandomBytes`.
