RFR: 8356032: createAutoconfBundle.sh downloads to local directory

[Ivan Bereziuk]

Fixed a small issue in createAutoconfBundle.sh where we CD to `build/autoconf` folder before it's created.
As result, we end up with `m4` and `autoconf` downloadable and unpacked folders in CWD.

By a chance, I did few other improvements:
* colored logs for easier log reading
* resolved `/../../` in the path to ease log reading.
* `http://yum.oracle.com` was permanently relocated to `https`.
