I've reworded this to:

	bool "Virtual filesystem support"

to be more consistent with the existing VDE2 option. Indeed, indicating
"Enable" in an option is not very useful: it's pretty obvious than an
option is here to "Enable" something. Also the "in Qemu emulator" is
not very useful either, since the option being added is already a
sub-option of the main host-qemu option.

I've applied to next after this minor change. Thanks!

Thomas
