This "child" test was actually reading itself (whoops!). Instead, pass
the address of the string to be read back from the child and read that.

This implementation has some limitations as documented in the header,
however, threads must be suspended in order to use the register capture
debug API so this is somewhat useful for now in the context of
generate_dump.
Also, refactor some child-object retrieval helpers used in a few places.

uname() seems to hang, sometimes, perhaps when then network is in a bad
state. Additionally, this way allows getting a minimal amount of version
information via zx_system_get_version().

With this `generate_dump <somepid>` generates a valid and somewhat
plausible (but still quite incomplete) minidump.
As an example, on a running Fuchsia system, `ps` reported the pid of
"netstack" as 6062, followed by `generate_dump 6062`, copy minidump.6062
to host, and run Breakpad's minidump_dump on the generated dump file,
resulting in:

This looks roughly correct in that it has a bunch of threads (without
much data) and a reasonable looking module list.

Mostly sensible implementation for x64 via cpuid. It's too early for
Fuchsia to have a version number, so nothing is reported for those
fields. ARM64 isn't implemented at all and would hit a lot of
NOTREACHED()s.

Adds beginning ProcessReader implementation for Fuchsia which currently
only reads modules from the target process. ModuleSnapshotFuchsia
implemented enough to pull out CrashpadInfo, which in turn is passed
through ProcessSnapshotFuchsia, which is enough to get
CrashpadInfoClientOptions.OneModule to pass.
