Multi-user MTP, handle secondary user boot.
Watch for BOOT_COMPLETED, and dispatch any current USB state or
mounted volumes which may have already occured. This specifically
handles starting of secondary users.
The current MTP kernel driver at /dev/mtp_usb is exclusive, meaning
only one process can have it open. To solve this, the framework
cycles the USB host stack when switching users, giving the new
user's media process a chance to claim the kernel device. We only
start an MtpServer when we're the active user.
