fix(pnpm): allow EBUSY when deleting node_modules (#6826)

## What's the problem this PR addresses?

EBUSY should be allowed, if `node_modules` is an active docker
mountpoint where rmdir attempts to unmount it which fails because there
are open files.

Closes #4373 #4974 #4259 #1184 #4172 

## How did you fix it?

Allow EBUSY to not block "clearing" node_modules.
