   Add check for autoreconf dependency to autogen.sh and refactor -if to long forms of optional arguments.

   Impact

   • Add a functional change to improves error handling to provide a more helpful message if autoreconf is not found.
   • Add a non-functional refactor to change the autoreconf optional arguments from -if to –install –force.
   • These changes align with the format of autogen.sh on the bitcoin repo

   On my system, the current error message is already quite descriptive:

   0$ ./autogen.sh 
   1./autogen.sh: 3: autoreconf: not found

   I agree, but the error message could be made even more helpful for those less familiar with the build process.

   Since autoreconf is a part of the autoconf package, directing users to install autoconf (rather than just indicating that autoreconf is missing) makes it clearer which package to install.

   autoconf is named consistently across popular Unix-based package managers, so this saves a step for users who try to install autoreconf:

   0apt-get install autoconf
   1dnf install autoconf
   2pacman -S autoconf
   3install autoconf
   4zypper install autoconf
   5apk add autoconf
   6nix-env -iA nixpkgs.autoconf
   7emerge dev-util/autoconf
