install-deps.sh: move functions above all "main" script body

Previously, the main part (top level body) of the script started and
then some function definitions occurred and then the main part of the
script resumed after that. I, and others, find this confusing so this
change moves the function definitions to occur before the main body of
the install-deps.sh script.
