Don't put files in subdir when extracting

[jssblck]

Overview

Updates the EmbeddedBinary logic to suffix the fossa-vendor directory name with a UUID instead of nesting a UUID folder inside.

This provides complete isolation to multiple callers, such that even if they (or a system process) cleans up the parent after they're done they don't mess with other callers.

Acceptance criteria

Integration tests pass again

Testing plan

Relying on integration tests- if this breaks anything with extraction we'll get way more errors, if this fixes the issue observed in other PRs we'll get none.

Risks

None

Metrics

None
