Fixes De data is not backed up correctly when user locked (1/n)

https://android.googlesource.com/platform/frameworks/native/+/fda19ecdd6df8f43d3368781a633792723fb9965/cmds/installd/InstalldNativeService.cpp#933

When an APK is stage installed, snapshotAppData(..., FLAG_STORAGE_DE)
is called before user unlocked. The function bails out early at #937
because the folder is still encrypted.

We should move the if block at #958 above so we can back up De data
correctly even when Ce directories not ready.

Note we have to check if the De folder exists before making a copy.
