util/util_readme: Don't recommend running this script with "sh"

util/util_readme/util_readme.sh is specifically a bash script and
requires bash-specific features such as "[[". It doesn't work when run
with a "sh" shell that only implements POSIX features, such as dash.
Thus, tell the user to run the script directly, in which case the #!
line is used.
