macOS builds are broken

[elprans]

The macOS EdgeDB build started failing with the below error for no apparent reason. Need to investigate and fix/workaround. Possibly, replace the use of rsync with an equivalent Python snippet.

Build is fixed but found another problem: for some reason ln -sf /Library/Frameworks/EdgeDB.framework/Versions/1-alpha4/lib/edgedb-server-1-alpha4/bin/edgedb-server _artifacts/install/edgedb-server/Library/Frameworks/EdgeDB.framework/bin/edgedb-server-1-alpha4 doesn't work and that path in the file list ends up being invalid.

I removed the unversioned shim from the package. I need to replace it with the versioned symlink before closing this.

[ambv]

The symlink problem is fixed. The test nightly run failed on running tests though (the server didn't turn up). I'll be starting another run when geldata/gel#1518 is merged.

[ambv]

I'm looking at the successful run and it still took over 6 seconds for the server to start. We time out at 10. Maybe we should allow for a longer timeout?

[elprans]

Sure, let's give it 20 for a better margin.
