kconfig: fix submenu rendering of negative dependencies

Browse source 
The Kconfig frontend should render options that depend on a
previous option in the submenu of that previous option. But
currently, this breaks for negative dependencies. For example,
option FOO may be rendered in the submenu of option BAR, despite
FOO actually depending on !BAR.

Let's fix this ironic rendering by modifying Kconfig to explicitly
check negative dependencies.

I've only tested locally on x86, but as far as I can tell, this only
changes how 2 options are rendered in the menu:
1. NTFS3_FS, no longer in the NTFS_FS submenu, and
2. MTD_BLOCK_RO, no longer in the MTD_BLOCK submenu.
