epsxe: fix link with openssl (#71920)

* epsxe: fix link with openssl

Epsxe is hardcoded to build with openssl-1.0 (using libcrypto.so.1.0.0),
but current nixpkgs contains openssl-1.1, which provides
libcrypto.so.1.1.

This patchs just uses the previous version of the library.

* epsxe: use autoPatchelfHook instead of manual rpath overriding

This simplifies the file AND generates failures at build time if a
needed dynamic library is not found during build time.
