Logging is always a compromise between clarity and detail. The main use case for dumping VMA's is when FIXTURE_SETUP() fails, and is less important for enclaves that do initialize correctly. Therefore, print the segments and /proc/self/maps only in the error case.
Finally, if a single test ever creates multiple enclaves, the amount of log lines would become enormous.
