Deorbit ALLOW_SHARED_TEXTREL

[emaste]

Summary

We want to avoid .text relocations in shared objects. libcrypto was the only consumer and it is now fixed, so remove the now-unused support for disabling the linker warning.

This might make harder future imports of buggy libraries in future. OTOH, the LD_FATAL_WARNING knob provides the same functionality still.

Yeah, my hope is that this might encourage a future importer of a buggy library to fix it first, and if not at least the ld warning will come out in the log.
