libsandbox: preserve more SANDBOX env vars
While we took pains to preserve the LD_PRELOAD setting, this doesn't
help us too much in practice. If a process is going out of its way
to blow away LD_PRELOAD, chances are good it's blowing away all vars
it doesn't know about. That means all of our SANDBOX_XXX settings.
Since a preloaded libsandbox.so is useless w/out its SANDBOX_XXX
env vars, make sure we preserve those as well.
These changes also imply some behavioral differences from older
versions. Previously, you could `unset` a sandbox var in order
to disable it. That no longer works. If you wish to disable
things, you have to explicitly set it to "".
