internal/frontend: exclude paths case-sensitively
Provide a way to exclude paths exactly (case-sensitively).
The usual exclusion mechanism is case-insensitive, which is a problem
for those who want to exclude only particular casings of their module.
For example, IBM would like their name in all caps, but some older
packages were published under "ibm".
Exclude "github.com/ibm/sarama".
For golang/go#71342.
