ArmVirtPkg: Remove redundant library instances in ArmVirtQemuKernel.dsc

ArmVirtPkg: Remove redundant library instances in ArmVirtQemuKernel.dsc

Commit 9a67ba261fe9 ("ArmVirtPkg: Replace obsoleted network drivers
from platform DSC/FDF") incorrectly added the BaseCryptLib, OpensslLib
and IntrinsicLib to "ArmVirtPkg/ArmVirtQemuKernel.dsc", it's redundant
and the library instances from "ArmVirt.dsc.inc" is already sufficient.

This patch also adjust the order of network drivers in "ArmVirtPkg/
ArmVirtQemuFvMain.fdf.inc" to make it same as the DSC file.
