fix(lambda-nodejs): docker build is not working

[ncaq]

fixes #10881

fix from sh to bash

lib/bundlers.ts actually uses not sh but bash,
bash is a good way to test.

lock yarn version

aws-lambda-nodejs have issue

• npm install -g yarn · Issue #6 · nodejs/corepack
• npm install yarn --global fails in docker container · Issue #8358 · yarnpkg/yarn

From issue comment,

For future reference, you can (should) pin your version rather than use whatever the latest is on npm (by using yarn@1.22.6, etc) - it's a good practice anyway regardless of the conditions, as you never know which bug could slip by us. You can also use the yarn-path setting to ensure that upgrades go through the appropriate review processes (including CI).

yarnpkg/yarn#8358 (comment)

So we'll follow it.

And from issue comment,

Fwiw we don't plan to add any more features to Yarn 1, as all of our resources have shifted to Yarn 2. The past few commits have been aimed toward making the transition a bit easier, in particular thanks to the Corepack initiative which we hope will make it easier to use Yarn (both 1 & 2) by removing the need to manually install them.

yarnpkg/yarn#8358 (comment)

There's not much need to be concerned with the latest version of 1.

allow execute command for non root user

amazon/aws-sam-cli-build-image-nodejs12.x don't have user that index is 1000.
So create non root user.

/ in amazon/aws-sam-cli-build-image-nodejs12.x permission is 700.
change to allow execute command for non root user.
I really don't want to change around the permissions,
but I don't have a choice.

@ncaq what do you mean exactly here?

@ncaq what do you mean exactly here?

The lib/bundlers.ts actually uses not sh but bash.

aws-cdk/packages/@aws-cdk/aws-lambda-nodejs/lib/bundlers.ts

Line 122 in 3839796

command: ['bash', '-c', command],

So test code use bash likewise.
