localmodconfig: Add config depends by default settings
Currently localmodconfig will miss dependencies from the default option. For example: config FOO default y if BAR || ZOO If FOO is needed for a module and is set to '=m', and so are BAR or ZOO, localmodconfig will not see that BOO or ZOO are also needed for the foo module, and will incorrectly disable them.
