Test disassembly of .text sections of sample binaries

[langston-barrett]

Some tests for disassembly of some small binaries. Having a test suite like this is nice because

1. It will benefit from any work done upstream on sample-binaries, which can benefit multiple projects across Galois
2. It is really easy to compile a hairy binary, toss it into tests/data, increment the expected number of tests, and test that Flexdis86 can disassemble it.

Similar tests for the other disassemblers are based on this code: https://github.com/travitch/dismantle/blob/master/dismantle-tablegen/src/Dismantle/Testing.hs. It uses objdump as an oracle and makes sure that we can roundtrip every instruction that objdump knows about.

@kquick suggested that we use elf-edit instead of creating the .bin files with objcopy, which seems much better.

@kquick I think we'll need an update to the Hydra configuration for this branch to work. If you point me in the right direction, I'm happy to give it a shot.

NTS: Kevin says that for this to move forward, we should allow an environment variable to specify the locations of the additional test binaries.

I've updated this with the environment variable configuration, and there's a WIP PR to the Fryingpan config files that will let us test it: https://gitlab-int.galois.com/binary-analysis/nix/-/merge_requests/5

[langston-barrett]

We've merged the configuration changes, so by Monday we should have green checks from Fryingpan. Thanks to @kquick for helping me get Fryingpan configured!

Build is passing on S2N, Kyber, and saw-script, failing on SFE and Macaw, seemingly due to unrelated goings-on in Renovate-x86:
