libsandbox: push down constructor init
Since every consumer of sb_open gets a copy of the sbio_open data, push
the init of this into the .data section of the respective consumers to
avoid the runtime overhead.
This just leaves sandbox_lib setup in the constructor function, but that
is only needed by the execve wrapper, so push down init of that to the
existing sb_init logic which happens before our execve wrapper gets used.
