azure: Prepare configuration for 4-core machines This commit updates some of our assorted Azure/CI configuration to prepare for some 4-core machines coming online. We're still in the process of performance testing them to get final numbers, but some changes are worth landing ahead of this. The updates here are: * Use `C:/` instead of `D:/` for submodule checkout since it should have plenty of space and the 4-core machines won't have `D:/` * Update `lzma-sys` to 0.1.14 which has support for VS2019, where 0.1.10 doesn't. * Update `src/ci/docker/run.sh` to work when it itself is running inside of a docker container (see the comment in the file for more info) * Print step timings on the `try` branch in addition to the `auto` branch in. The logs there should be seen by similarly many humans (not many) and can be useful for performance analysis after a `try` build runs. * Install the WIX and InnoSetup tools manually on Windows instead of relying on pre-installed copies on the VM. This gives us more control over what's being used on the Azure cloud right now (we control the version) and in the 4-core machines these won't be pre-installed. Note that on AppVeyor we actually already were installing InnoSetup, we just didn't carry that over on Azure!
