Kaushik Iska b2d91d920a [web] Update build_web_compilers to 2.7.1 (flutter/engine#14305)
* [web] Update build_web_compilers to 2.7.1

This was causing problems with the dart compiler location
for web.

The compiler seems to be present in out/host_debug_unopt/dart-sdk/lib/dev_compiler/kernel/amd/dart_sdk.js as opposed to out/host_debug_unopt/dart-sdk/lib/dev_compiler/amd/dart_sdk.js

* also update build_runner
