[roll] Roll fuchsia [vfs] make most of test_utils private
Except for build_flag_combinations, nothing in test_utils should have
ever been exported. Remove the (mostly) frivolous uses and make it
pub(crate) for now. After the following refactors to the vfs unit tests,
most of it should go away, which can be directed by dead code analysis
now that it is internal to the crate.
There were already some things that weren't used, hidden by the fact
that these were pub, which are deleted immediately.
