Zygote: limit the bounding capability set to CAP_NET_RAW

Prevent a zygote spawned application from acquiring
capabilities other than CAP_NET_RAW.  The only Zygote
accessible program on Android which grants capabilities
is /system/bin/ping (CAP_NET_RAW), so we don't need to
keep the other capabilities in our bounding set.
