Suggestion: beads install script should re-ad hoc sign the bd binary on macOS

[mikehearn]

codesign --remove-signature bd
codesign --force --sign - ./bd

If you don't do this then macOS interrogates Apple servers to do a malware check every time the binary is run, because it has an ad hoc (machine specific) signature that's not for the current machine. This makes running bd very slow.

I'm actually no longer sure this is a real bug. Beads has invisible timeouts for connecting to its own server that cause it to hang at startup, which looks a lot like the way macOS hangs a process start when code signing isn't done. It's possible that resigning it got mixed up with something else that caused it to seem faster when startup time didn't change.
