fix(docker): stage curl libs under /usr/lib64, not /lib64

ldd reports library paths as /lib64/... (the legacy short path).
quarkus-micro-image:2.0 has /lib64 as a symlink to /usr/lib64, so
COPY --from=curl-builder /out/ / collides when trying to write into
/lib64 (cannot copy to non-directory).

The fix: in the curl-builder stage, translate /lib64 -> /usr/lib64
(and /lib -> /usr/lib) before installing each library, so the final
image gets libs under /usr/lib64 and doesn't touch the /lib64 symlink.
