chore(3p/josh): update josh to recent master commit r/5895

It's been a long time since we updated josh, almost 400 commits in
between. I read through the entire changelog, and here are relevant
josh commits from in between that might be interesting to us:

  38eecee Fix optimisation bug for compose filter (#1159)
  e1d10b6 Add :rev(...) filter
  0f1a07b Initial implementation of refs locking (#929)
  88cea2a Initial work on meta repo support
  030ad93 Change magic refs to include "for"
  28b1d75 Add split changes feature (#904)
  1f908d7 Discover filters only on HEAD (#774)
  a368d8f Make --require-auth only apply to push
  8d80230 Add :linear filter (#741)
  3460ec2 Implement redundant refs filtering (#700)
  55b4e50 Implement stacked changes support (#699)
  ea1f814 Handle @sha urls by creating magic ref (#690)
  883a381 Run filter discovery only on changed refs (#685)
  4bb004f Prepend refs/heads to base parameter as default (#664)

Of particular interest is a368d8f, which allows us to drop our
authentication patch and use the standard --require-auth flag again.

The default behaviour of dropping signatures on commits (which are
invalid after filtering) has also been changed in josh, now only
occuring when the `:unsign` filter is present. Since this breaks
commit hashes with our existing exported histories, we are opting to
set a `:unsign` filter prefix on all proxy requests to ensure that the
hashes stay consistent.

During this update we found a bug (josh#1155) which was fixed in the
commit that this CL moves josh to.
