media: dvb: fix DVB_MMAP dependency
Enabling CONFIG_DVB_MMAP without CONFIG_VIDEOBUF2_VMALLOC results
in a link error:
drivers/media/dvb-core/dvb_vb2.o: In function `_stop_streaming':
dvb_vb2.c:(.text+0x894): undefined reference to `vb2_buffer_done'

This adds a 'select' statement for it, plus a dependency that
ensures that videobuf2 in turn works, as it in turn depends on
VIDEO_V4L2 to link, and that must not be a module if videobuf2
is built-in.
