Detect Azure Linux properly

[daandemeyer]

Fixes #2988

[reubeno]

Thanks for the quick turnaround! I tried your change and confirmed that it resolved the issue I was running into. I can now successfully run mkosi -t disk without any other custom conf and get an image.

(I can't yet do the same within my cloned copy of this repo, but that's because mkosi/resources/mkosi-tools/mkosi.conf.d/10-azure.conf references erofs-utils, which doesn't presently exist in Azure Linux. Removing that unblocks the latter. Should I file a separate issue/PR for that?)

@reubeno erofs-utils was there last week. Can you figure out why it was removed?

@daandemeyer microsoft/azurelinux#9971 added EROFS support in the Azure Linux 3.0 kernel, but I can't see any indication that the userspace tools (i.e., erofs-utils) were ever present.

With that said, they seem like they ought to be in the distro too now that kernel support has been enabled. FYI to @christopherco

JFYI: we're now at erofs-utils 1.8.1, yet recently there are some new hotfixes submited.
I think I will release erofs-utils 1.8.2 this weekend.

It was actually a bug in mkosi uncovered by this fix, so it indeed never was available in azure linux.

Thanks for the quick turnaround and resolution! I really appreciate the effort you've put into supporting Azure Linux.

Hi @christopherco, in case that erofs-utils may be interesting, I've released erofs-utils 1.8.2 yesterday.
and the current use cases (maybe incomplete) are documented on the website too: https://erofs.docs.kernel.org
