tests: remove slow /proc/kallsyms tests

test_local_proc_kallsyms and test_local_proc_kallsyms_with_modules()
each take a second or two on my Fedora laptop, an order of magnitude
slower than the next slowest test. We already have the synthetic test
case, so let's use that. We can bring these back in a more optimized
form if needed.
