Ports: Update x264 to b35605a

Also update the patch for the configure script to use a portable shebang
(/bin/bash does not exist on NixOS) and add nasm to the nix shell to
make it build:

[x264/configure] + ./configure --host=x86_64-pc-serenity --enable-shared
[x264/configure] Found no assembler
[x264/configure] Minimum version is nasm-2.13
[x264/configure] If you really want to compile without asm, configure
                 with --disable-asm.
