localmodconfig: Add config depends by default settings

Browse source 
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.
