[roll] Roll fuchsia [superproject] Roll scudo [fuchsia] Tune PrimaryGroupSizeLog to reduce fragmentation.

21U is the default group size, which demonstrates ~15mb reduction
in heap size for some highly fragmented heaps on Fuchsia, and
a general 5mb savings when devices are under no load.

Microbenchmarks show no performance regressions, but most of our
benchmarks perform no significant mallocs. So we are choosing the
default setting, and monitoring for potential performance
issues.

Obtaining the source

First install Jiri.

Next run:

$ jiri init
$ jiri import minimal https://fuchsia.googlesource.com/integration
$ jiri update

Third party

Third party projects should have their own subdirectory in ./third_party.
