Fix install_prereqs.sh scripts for building on Fedora

There were several issues with the install_prereqs.sh script:

- It was trying to run scripts/lirc.sh *before* installing packages,
  which would cause everything to fail.

- It added `PACKAGES_DEBIAN` to `PACKAGES_FEDORA`, resulting in a failed
  package install.

- It fails to install `wget`, which is required by one of the builds.

- If fails to install `autoconf` and `libtool`, causing configure
  script invocations to fail

Note that even with these fixes the libetpan build still fails; that will
need to be addressed in a future PR.
