[FFmpeg-cvslog] avcodec/Makefile: Only compile nvenc.o if needed

ffmpeg | branch: release/4.4 | Andreas Rheinhardt <andreas.rheinhardt at outlook.com> | Wed Jan  5 14:59:21 2022 +0100| [717c7f4ae9eb8e80042404a222d63dc941d13216] | committer: Timo Rothenpieler

avcodec/Makefile: Only compile nvenc.o if needed

This fixes compilation errors in case nvenc is enabled
(e.g. autodected) with both nvenc-based encoders disabled
because nvenc uses ff_alloc_a53_sei(), yet only the nvenc-based
encoders require atsc_a53.
(This error does not manifest itself in case of static linking
(nothing pulls in nvenc.o), but it exists with shared builds.)
