[options] Fix dict order py38 incompatibility

python-3.8 dict changes introduce a traceback during our config file
parsing for options with `-` characters in them.

Fix this by changing an iteration of the dict keys from `dict.keys()`
that returns a dict_keys view, to `list(dict)` which returns a list copy
of the keys.

Closes: #2206
Resolves: #2207
