The conversion was performed with a few sed commands:
find -name '*.asm' | xargs sed -i -e 's/data.str \("[^"]*"\) data.8 0$/data.strz \1/g'
find -name '*.asm' | xargs sed -i -e 's/data.str \("[^"]*"\) data.8 0 /data.strz \1 /g'
find -name '*.asm' | xargs sed -i -e 's/data.str \("[^"]*"\) data.8 0x00 /data.strz \1 /g'
