ArmVirtPkg/PlatformBootManagerLib: return to "-kernel before boot devices" 

Move the TryRunningQemuKernel() call back to its original place. This
improves the UEFI boot time for VMs that have "-kernel", many disks or
NICs, and no "bootindex" properties. A well-known example is
guestfish/libguestfs.

For more info on the TryRunningQemuKernel() location, see the following
commits: 23d04b58e2, a78c4836ea, 158990b941.
