ebce92b is described below
commit ebce92bf8d71f8a6e8af1c6cf6ba335faf9d67c8

providers: Fix determinism issue
We saw builds where runtime providers were sometimes changing order and the
build result was therefore non-deterministic. For example it could show:
DEBUG: providers for lib32-initd-functions are: ['lib32-lsbinitscripts', 'lib32-initscripts']
or
DEBUG: providers for lib32-initd-functions are: ['lib32-initscripts', 'lib32-lsbinitscripts']
which could cause a test to pass or fail.
This change ensures we don't rely on the random order of dictonaries in
memory and act deterministically.
