@rollup/plugin-legacy issue in windows

[patak-dev]

Is your feature request related to a problem? Please describe.

@rollup/plugin-legacy doesn't work in Windows.

Here is a repro using the vanilla starter:
https://github.com/matias-capeletto/vite-rollup-plugin-legacy

Describe the solution you'd like

The problem seems to be in https://github.com/rollup/plugins/blob/master/packages/legacy/src/index.js#L15
It is comparing the resolved path with Vite normalized id, so the check fails

in exports it is C:\Labs\vite-rollup-plugin-legacy\legacy.js

and the id is /Labs/vite-rollup-plugin-legacy/legacy.js

Describe alternatives you've considered

I tried to use normalizedPath from vite, but there is an internal resolve in the plugin. I do not know if there is an option to avoid normalized paths in windows for the ids. I'll open another issue for include/exclude options in several plugins that could be also related.

Additional context

vite version: 2.0.0-beta.27
Operating System: Windows 10 Home, 10.0.18363 N/A Build 18363
