[PATCH][honister] arm/edk2-firmware: correctly set the target prefix in Clang builds

[Ross Burton]

We set GCC5_AARCH64_PREFIX so the tools are prefixed correctly in GCC
builds, but didn't set CLANG38_AARCH64_PREFIX. This meant the clang build
used the host objcopy, which may not know about the target architecture.

Also these can just be the prefix and not a full path, as the binaries
are on $PATH.
