The output of projects build --build-order and of required-os-pkg is correct but not reproducible: both are built by iterating Python sets, so the order followed the hash seed of the Python process, and two runs of the same invocation could print different orders. Makes debugging harder, so make the output stable.

cmds.projects.CmdBuild: Sort build order

The build order printed by projects build is not reproducible: calculate_order() picks the next module by iterating all_deps, a set, so the order among modules that are ready at the same time depends on the hash seed of the Python process, and two runs of the same invocation can print different orders.

Select the next module from the sorted set instead. The order stays topologically valid, and is now identical across runs and hash seeds. Sort the unresolvable-dependency error message the same way, so that it is stable, too.

cmds.projects.CmdRequiredOsPkg: Sort output

The list of OS packages printed by required-os-pkg is not reproducible: the packages are collected in a set, and the set's iteration order depends on the hash seed of the Python process, so two runs of the same invocation can print the same packages in different orders.

Print the sorted list instead. The order of a package list is meaningless to the package manager, and the output is now stable across runs and hash seeds.

cmds.projects.CmdBuild: Sort build order ... 7af9a705d7

The build order printed by projects build is not reproducible:
calculate_order() picks the next module by iterating all_deps, a set, so
the order among modules that are ready at the same time depends on the hash
seed of the Python process, and two runs of the same invocation can print
different orders.

Select the next module from the sorted set instead. The order stays
topologically valid, and is now identical across runs and hash seeds. Sort
the unresolvable-dependency error message the same way, so that it is
stable, too.
