fix: don't trash optional dependencies that fail to install due to incompatible platform

[paulrutter]

This PR is a proposed solution for multiple reported issues regarding failed optional dependencies that are platform specific.
See #4828, #7961 and possibly related PR #8077.

It can be reproduced as follows:

• mkdir test && cd test
• npm init -y
• npm i -D rollup
• Read package-lock.json - observe 18 OS/CPU@rollup/* package variants are listed
• rm package-lock.json
• npm i
• Read package-lock.json - observe only 1 OS/CPU @rollup/* package variant is now listed for the current platform

With this PR, the package-lock.json will remain to contain the initial 18 rollup related dependencies, as any optional failure due to incompatible platform (EBADPLATFORM) will not lead to trashing the node.

The side-effect of this is that all platform specific dependencies will be present on all platforms (just an empty directory where the platform doesn't match). But it does solve the issue at hand.

I would need help writing a proper unit test for this scenario though. With the steps below, i did manage to test my PR and see that it has the desired effect:

• node . i -D rollup
• Read package-lock.json - observe 18 OS/CPU@rollup/* package variants are listed
• rm package-lock.json
• node . i
• Read package-lock.json - observe 18 OS/CPU@rollup/* package variants are listed still
