package/heimdal: install compile_et

compile_et is not installed anymore by heimdal since version 7.0.1 and
https://github.com/heimdal/heimdal/commit/e40ef47b57f3c62f94c4056f02ced3af2ed083ca

So remove the broken symlink and install it manually as it is needed for
samba4 because compile_et provided by e2fsprogs raises a build failure
