The new C test takes 25 seconds on QEMU-RISC-V, wheras the shell version
takes 332 seconds.
Even with the latest optimizations to atf-sh this test still takes a few
seconds to startup in QEMU. Re-writing it in C reduces the runtime for a
single test from about 2-3 seconds to less than .5 seconds. Since there
are ~80 tests, this adds up to about 3-4 minutes.
This may not seem like a big speedup, but before the recent optimizations
to avoid atf_get_srcdir, each test took almost 100 seconds on QEMU RISC-V
instead of 3. This also significantly reduces the time it takes to list
the available test cases, which speeds up running the tests via kyua:
```

The speedups are even more noticeable on CHERI-RISC-V (since QEMU runs
slower when emulating CHERI instructions):
