adb: fail better in install-multiple.

If we're failing out, don't print any messages from the shutdown code:
it's not interesting (and actively confusing!) to talk about the
"Success" of finalizing an aborted session.

Also fail early if stat fails the first time (we have to tell
PackageManager how much data to expect, for some reason).

Also use `bool` as the boolean type and add quotes around filenames in
error messages.

`install_multi_package` looks like the same nonsense copy & pasted, but
I don't know what that is, and haven't seen any bug reports, so I'm
ignoring that for now.
