topjohnwu da723b207a Allow 3rd party code to load pre-specializing 
Magisk's policy is to never allow 3rd party code to be loaded in the
zygote daemon process so we have 100% control over injection and hiding.
However, this makes it impossible for 3rd party modules to run anything
before process specialization, which includes the ability to modify the
arguments being sent to these original nativeForkAndXXX methods.

The trick here is to fork before calling the original nativeForkAndXXX
methods, and hook `fork` in libandroid_runtime.so to skip the next
invocation; basically, we're moving the responsibility of process
forking to our own hands.

Billy Laws 947a7d6a2f Support rootwait cmdline parameter on legacy SAR 
On devices where the primary storage is slow to probe it makes sense to
wait forever for the system partition to mount, this emulates the
kernel's behaviour when waiting for rootfs on SAR if the rootwait
parameter is supplied.

This issue was encountered with some SD cards on the Nintendo Switch.
