Switch from sourceforge to github for ipmitool

Currently CI fails on build ipa image on xenial, because downloading
with wget from sourceforce is giving SSL error. Start using the
github mirror, that is not having this problem.

Additionally added autoconf, autogen, automake, and libtool
to the build requirements as the new ipmitool package is based
off of repository commit history tags and did not contain
a pregenerated configure file.
