libx265 need nasm 2.13 for version >2.6 #166

Hi, When testing different version of libx265 I've found that nasm is not installed but needed in libx265 version 2.7 (see patch note). That lead to having libx265 running 6 times slower.

To fix this we need to add nasm >= 2.13 in the packages list but debian and ubuntu only have older version in their repositories.

I've made a workaround by downloading directly the debian multimedia package and installing it with dpkg. RUN wget http://www.deb-multimedia.org/pool/main/n/nasm-dmo/nasm_2.13.01-1.1_amd64.deb && dpkg -i nasm_2.13.01-1.1_amd64.deb

But I think it's not the proper way to do it.

Using 18.04 as base potentially solves this issue, 2.13+ is bionic package. https://packages.ubuntu.com/bionic/nasm
