Amir Masoud Abdol c3d3e73124 Prefer GSS.framework on macOS over libgssapi_krb5.tbd when using vcpkg
On macOS, vcpkg toolchain sets the value of CMAKE_FIND_FRAMEWORK and
CMAKE_FIND_APPBUNDLE to LAST which causes an issue when it comes to
GSSAPI. This change in behavior leads to FindGSSAPI.cmake finding
`usr/lib/libgssapi_krb5.tbd → Kerberos.framework` instead, which is not
exactly what we want, and it misses some necessary symbols, and as a
result Network fails to build.¹

We need to make sure that we find `GSS.framework`. Here by dropping the
alternative name on Apple platform, we end up getting the Framework
even if vcpkg prefer finding the framework LAST.
