sci-misc/boinc: Fix typos in init script

This commit fixes Gentoo Bug #626958
  "sci-misc/boinc-7.6.33-r5 typos in /etc/init.d/boinc"

In five places the eerror function was spelled "eeror", which is
obviously wrong. This commit fixes that.

As the init script isn't correctly working in all error cases without
these fixes, the ebuilds got revision bumped to forece the
installation of the fixed version.
