[libuv] Bump to 1.16.1 and fix minor build issues

NOTE: The build has the folllowing warning output

    Unescaped left brace in regex is deprecated, passed through in
    regex; marked by <-- HERE in m/\${ <-- HERE ([^ \t=:+{}]+)}/ at
    /hab/pkgs/core/automake/1.15/201705132 14259/bin/automake line 3936.

I believe this is actually a problem in automake 1.5.
