package/elfutils: set program-prefix to default ("eu-")

Elfutils program names collide with binutils' binaries. By default
applications provided by elfutils are prefixed with "eu-", but in
Buildroot that setting is overridden by pkg-autotools.
The option in pkg-autotools rules was added to avoid including a target
triple in some packages as a prefix, so restore elfutils default
behaviour by adding a "eu-" program-prefix.

[Thomas: add comment in the .mk file explaining why we have a custom
program prefix, as suggested by Arnout.]
