dep-resolv: Fix --no-include-dependencies to have same default.

When I added the flag yesterday it changed the value of
'include-dependencies' for users who had never referenced it in their
config. This was not intentional.

Users who have set the option explicitly (either by using default config
file or from a generated config file) should see no change here.
