Define MODVERSION in a more reproducable way.
We define MODVERSION to make sure the libebl backend modules match the
elfutils build when we dlopen them. Using hostname and date makes it very
hard to create reproducable builds. Define them a little more reproducable
using LIBEBL_SUBDIR, eu_version and ac_cv_build.
