internal/frontend: remove local map of case sensitive excluded paths

go.dev/cl/761521 introduced an exact: prefix used to specify case sensitive paths that need to be excluded.

We can now remove the map that previously handled case sensitive exclusion. A separate CL merges the outstanding case sensitive excluded paths into excluded.txt.

For golang/go#77822
