V4L/DVB (9485): ivtv: remove incorrect V4L1 & tvaudio dependency

ivtv used tvaudio in the past and at the time tvaudio required V4L1.
Since tvaudio is no longer dependent on V4L1 and since ivtv actually
no longer uses tvaudio at all, this is no removed from Kconfig.

Without this patch ivtv won't be build if V4L1 is disabled.
