Linux sandbox: report TSYNC status in chrome://sandbox
TSYNC is a new sandboxing flag for seccomp that was recently added to
the Linux kernel.
If TSYNC is supported by the kernel, it is automatically used when enabling
seccomp-bpf).
When seccomp-bpf is enabled, we now report if TSYNC is supported by the kernel
in chrome://sandbox.
This allows users and developers to check their level of sandboxing and to
know how the sandbox has been enabled on their running instance of Chrome.
