mandoline: lock down the linux sandbox more.

Previously, the mandoline sandbox allowed all system calls except for
access()/open()/faccessat()/openat(). This patch now uses the baseline
sandboxing policy (which will error on many common syscalls and will
crash on unwhitelisted calls). Added a few syscalls that we need for the
compositor to the explicit allow list.
