   With f16d4cd8c5412890ee0b73f4ef142b59d130e5d5 depends/config.guess gives aarch64-apple-darwin20.3.0 where before would give arm-apple-darwin20.3.0. Fix qt.mk accordingly.

   What is the current problem? Is this fixing a native M1 depends build, or a cross-compile? Why is this a "better" fix than what was added in #20482?

   native

   What is the current problem?

   Before this PR, after building depends the configure gives errors like:

   ld: warning: ignoring file /Users/joao/Projects/bitcoin-core/22054/depends/aarch64-apple-darwin20.3.0/lib/libQt5Widgets.a, building for macOS-arm64 but attempting to link with file built for macOS-x86_64
   Undefined symbols for architecture arm64:
     "qt_static_plugin_QCocoaIntegrationPlugin()", referenced from:
         __GLOBAL__sub_I_conftest.cpp in conftest-7867ef.o
     "qRegisterStaticPluginFunction(QStaticPlugin)", referenced from:
         __GLOBAL__sub_I_conftest.cpp in conftest-7867ef.o
   ld: symbol(s) not found for architecture arm64
   clang: error: linker command failed with exit code 1 (use -v to see invocation)
   

   Before it was depends/arm-apple-darwin20.3.0.

   Did not test it on Apple M1.
