prelink: Drop support for it

Prelink is being dropped by glibc in 2.36. It already causes issues with
binary corruption, has a number of open bugs and is of questionable benefit
without disabling load address randomization and PIE executables.

We disabled it by default a while back but left people able to use it.
We would be unable to maintain it alone without glibc support so remove
the remaining pieces.
