.profile created as root if it does not already exist

[hoyle-ub]

If a user does not already have a .profile when this script is run, the file is created with owner 'root', rather than the user who ran the script. There's probably a more elegant way to fix this, but I just added:

if [[ ! -f /Users/${consoleuser}/.profile ]]; then
su -l "$consoleuser" -c "/usr/bin/touch /Users/${consoleuser}/.profile"
fi

inside the if statement that sets the shellenv for M1 users.
