Don't defer zygote

Removing 'updatable' from zygote as zygote is started after apexd. All
APEXes are guaranteed to be activated at the moment.

Sequence of actions:
1) /data mounted. post-fs-data is triggered.
2) apexd starts. APEXes are activated. Init does not execute more
commands until the activation finishes.
3) all post-fs-data sections from other *.rc are executed.
4) zygote-start is triggered.

Test: device boots
Test: no following message on the logcat log
Could not restart 'zygote': Cannot start an updatable service 'zygote' before configs from APEXes are all loaded. Queued for execution.
