Make sure we have Yasm >= 1.2.0 available on Linux 64bit

Similar to #18831 (moved) we now need Yasm >= 1.2.0 available as the 64bit build breaks without it otherwise:

 8:23.07 /usr/bin/yasm -o jccolor-avx2.o -f elf64 -rnasm -pnasm -g dwarf2 -D__x86_64__ -DPIC -DELF -I/var/tmp/build/firefox-8ba4752bc100/media/libjpeg/simd/nasm/ -I/var/tmp/build/firefox-8ba4752bc100/media/libjpeg/simd/x86_64/   /var/tmp/build/firefox-8ba4752bc100/media/libjpeg/simd/x86_64/jccolor-avx2.asm
 8:23.07 media/libjpeg/jccolor-sse2.o
 8:23.09 /var/tmp/build/firefox-8ba4752bc100/media/libjpeg/simd/x86_64/jccolext-avx2.asm:56: error: undefined symbol `jsimd_rgb_ycc_convert_avx2.return' (first use)

and similar errors.
