ArmVirtPkg: Fix depex in kvmtool guest Rtc library 

The Rtc library for the kvmtool guest firmware configures the
RTC controller address range as runtime memory by calling the
gDS->SetMemorySpaceAttributes().
The SetMemorySpaceAttributes() function has a dependency on
the CPU Arch Protocol. If the CPU Arch Protocol is not
installed the call to set the memory attributes fails with
error code EFI_NOT_AVAILABLE_YET.

Therefore, set the library dependency on the CPU Arch protocol.
