sys-libs/pam: remove usr-ldscript support

Per news item 2024-01-05-usr-initramfs, we no longer support this use
case. It is fragile and hacky and leads to bizarre forms of load errors.

The functionality is, despite being called "split-usr", not really about
split-usr at all.

[sam: add bug #868306 ref.]
