runtime: use .openbsd.randomdata for startupRand #69781

OpenBSD has its version of AT_RANDOM, the .openbsd.randomdata ELF section documented at SPECS.randomdata. We should use that instead of reading from /dev/urandom.

Looking at this, just want to make sure this is the documentation you're referring to: https://github.com/openbsd/src/blob/master/libexec/ld.so/SPECS.randomdata
