Reset CrashpadInfo after CrashpadInfoReader tests

Browse Source 
In preference to (the reverted)
https://chromium-review.googlesource.com/c/crashpad/crashpad/+/923178
this does not share implementation with the tests in
snapshot/crashpad_info_client_options_test.cc. This is not done because
those tests use faked CrashpadInfo structures that are intentionally
differently sized than the current defintion of CrashpadInfo, meaning
that the scoped reset could overwrite past the end of the structure.

Not resetting these was causing CrashpadInfoClientOptions tests to fail
on Fuchsia, because dlclose() [legally] doesn't do anything, so
modifying the current binaries CrashpadInfo caused the expected values
from child .sos to be ignored. That could be worked around in that test
too, but it's probably better to clean up the global state in this test
anyway.
