Subject: [PATCH] plymouth/plymouth-pretrigger.sh: also trigger acpi subsystem

Trigger the acpi subsystem. This will ensure hv_vmbus gets loaded before
plymouth is started, which will make the graphics device become
available before plymouth is started too (and the keyboard ! which might
also be important for plymouth in some setups).

(cherry picked from commit d2846fdcce9b8de0edecdf0e06a4b86fc8de542c)
