Subject: [PATCH] dependencies: Use patched source-map with a performance fix.

https://github.com/mozilla/source-map/issues/370

This makes Webpack about 9% faster.  Before:

$ multitime -n9 -s0 node_modules/.bin/webpack --config-name=frontend --display=errors-only -p
===> multitime results
1: node_modules/.bin/webpack --config-name=frontend --display=errors-only -p
            Mean        Std.Dev.    Min         Median      Max
real        18.243      0.107       18.090      18.236      18.443
user        27.913      0.188       27.714      27.843      28.251
sys         2.028       0.043       1.933       2.039       2.074

After:

$ multitime -n9 -s0 node_modules/.bin/webpack --config-name=frontend --display=errors-only -p
===> multitime results
1: node_modules/.bin/webpack --config-name=frontend --display=errors-only -p
            Mean        Std.Dev.    Min         Median      Max
real        16.686      0.085       16.542      16.684      16.885
user        25.965      0.167       25.559      26.022      26.163
sys         1.965       0.064       1.807       1.998       2.010
