ANDROID: GKI: set vfs-only exports into their own namespace

Browse Source 
We have namespaces, so use them for all vfs-exported namespaces so that
filesystems can use them, but not anything else.

Some in-kernel drivers that do direct filesystem accesses (because they
serve up files) are also allowed access to these symbols to keep 'make
allmodconfig' builds working properly, but it is not needed for Android
kernel images.
