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

- *  The following functions define the column width of an ISO 10646
- *  character as follows:
- *  - The null character (U+0000) has a column width of 0.
- *  - Other C0/C1 control characters and DEL will lead to a return value
- *    of -1.
- *  - Non-spacing and enclosing combining characters (general category
- *    code Mn or Me in the
- *    Unicode database) have a column width of 0.
- *  - SOFT HYPHEN (U+00AD) has a column width of 1.
- *  - Other format characters (general category code Cf in the Unicode
- *    database) and ZERO WIDTH
- *    SPACE (U+200B) have a column width of 0.
- *  - Hangul Jamo medial vowels and final consonants (U+1160-U+11FF)
- *    have a column width of 0.
- *  - Spacing characters in the East Asian Wide (W) or East Asian
- *    Full-width (F) category as
- *    defined in Unicode Technical Report #11 have a column width of 2.
- *  - All remaining characters (including all printable ISO 8859-1 and
- *    WGL4 characters, Unicode control characters, etc.) have a column
- *    width of 1.
- *  This implementation assumes that characters are encoded in ISO 10646.
