add boklm back to list of taggers in relevant projects

@boklm used to be part of the old torbutton.gpg, but we switched over to separate key-rings per dev to make it a bit less opaque who was a valid signer. GPG keying files aren't necessarily the easiest thing to look at compared to a list in the build. We should add him to the list, even though he doesn't have any neeed commits tagged, which is the rubric I originally used when building that list.
