Update to v0.5.0 using cargo fails

[lukehsiao]

I'm excited for the new release! I notice when I try to update tectonic using cargo, I see the following failure.

error: failed to run custom build command for `tectonic_bridge_harfbuzz v0.2.0`

Caused by:
  process didn't exit successfully: `/tmp/cargo-installskpdaR/release/build/tectonic_bridge_harfbuzz-e75182cb6c8217ab/build-script-build` (exit code: 1)

     if you have checked out from Git, you probably need to fetch submodules:
         git submodule update --init
     This is needed because we are attempting to compile a local copy of Harfbuzz.

Yup, there was a packaging error in the tectonic_bridge_harfbuzz crate. I think that I should have it resolved once #781 goes through.

[pkgw]

OK, hopefully version 0.2.2 of tectonic_bridge_harfbuzz should fix this issue. Is anyone able to confirm?

[soruh]

It works for me.

Yup, cargo install tectonic working flawless.

I can also confirm that I was able to update to tectonic v0.5.1 just fine with the fix. I'd consider this issue resolved, and am closing the issue as a result. Thank you!
