The p9 crate API changed so that the new() function now returns a
result. Update the caller to match.
Additionally, the implementation also changed to use different syscalls
so update the seccomp filters to match.

Minijail's policy compiler complains when there's multiple
unconditional rules for a syscall. In most cases the rules
are redundant to common_device.policy.

TEST=Ran compile_seccomp_policy.py until it stopped
complaining.

This allows us to use export a directory to a VM with the
'--shared-dir tag:/dir' crosvm command line flag without relying
on seneschal. The fs device's policy already does the same.
