fix(uninstall): fix issues with uninstalling manifest-only drivers

[amoeba]

This primarily fixes a bug with dbc uninstall for manifest-only drivers where the extra folder we install alongside the driver manifest wasn't being removed. I also factored out the common logic related to removing the driver shared library and added some defensive checks to limit the impact of a maliciously-crafted driver manifest.

Ref #15

Ready for a review. This now uses Clean on the path and I was able to test the new logic in config.UninstallDriverShared.

Looks like there's still issues with the windows tests

I'm seeing if I can figure out what's going on in CI by surfacing the error (which I should have done originally).

Hrm,

Failed to rename sidecar folder. Something is wrong with this test: rename C:\Users\RUNNER1\AppData\Local\Temp\TestSubcommandsTestUninstallManifestOnlyDriver3321879900\001\test-driver-manifest-only C:\Users\RUNNER1\AppData\Local\Temp\TestSubcommandsTestUninstallManifestOnlyDriver3321879900\001\test-driver-manifest-only_windows_amd64_v1.0.0: The system cannot find the file specified.

I may need to log into my Windows machine to see if installing a manifest-only driver works on Windows.

Looks good now @zeroshade.
