fix(ubuntu): chown more safely

[mikehardy]

• make sure the root of android stuff is chowned for installation of completely new things if needed
• don't fail when recursively chowning specific android things, as they may not exist yet (i.e., platform-tools) when chown is attempted

[mikehardy]

This can be considered a follow-on to #406 - which is a nice performance boost but makes assumptions about the directories existing - linux will throw a non-zero exit code if you chown something that isn't there but using a || true in the shell means that you can blindly try the chown and it's fine if it fails

[mikehardy]

chown not required at all anymore it seems - less code == better
