[scudo] Delay allocations in the RSS check test
Summary:
D57116 fails on the armv7 bots, which is I assume due to the timing of
the RSS check on the platform. While I don't have a platform to test
that change on, I assume this would do.
The test could be made more reliable by either delaying more the
allocations, or allocating more large-chunks, but both those options
have a somewhat non negligible impact (more memory used, longer test).
Hence me trying to keep the additional sleeping/allocating to a
minimum.
