Update fix-reverse-dollar-signs.sh

I Used find -print0 and xargs -0 instead of find -print and xargs -L 1 allows for handling filenames with spaces or special characters more safely & I also removed the -L 1 option from the xargs command, as this is not necessary when using -print0 and -0 together.
