media: tuners: Kconfig: add some missing VIDEO_V4L2 dependencies

There are three tuners that depend on some functions inside
V4L2 core:

	$ git grep -l -E 'v4l2_[0-9a-zA-Z_]+\(' drivers/media/tuners/
	drivers/media/tuners/e4000.c
	drivers/media/tuners/fc2580.c
	drivers/media/tuners/msi001.c

Make them dependent of VIDEO_V4L2, as otherwise, this would happen:

	on x86_64:
	CONFIG_VIDEO_V4L2=m
	CONFIG_MEDIA_TUNER_E4000=y
