Ansible feature patch - install nasm rather than yasm

[Gary Buhrmaster]

In ffmpeg commit 4f9297ac3b39098547863d28fbc8d2a906d5be49 (from June 2017, derived from a libav patch from Oct 2016) nasm has been preferred over yasm for ffmpeg.

build: Prefer NASM assembler over YASM

NASM is more actively maintained and permits generating dependency information as a sideeffect of assembling, thus cutting build times in half.

And, indeed, the current mythtv configure script (derived/merged from the ffmpeg configure), prefers nasm, but falls back to yasm.

Test builds with nasm (rather than yasm) only lightly tested on recent fedora and centos systems.

Proposed patch follows:
