sys-devel/autoconf: [QA] Convert from eblits into an eclass, #586424

Convert the usage of eblits in sys-devel/autoconf into an equivalent
eclass. This makes the ebuilds more readable, more predictable and fixes
compliance with stricter versions of the package manager (i.e. a future
release of Portage).
