In the changes Jonas made in https://reviews.llvm.org/D117340 , a small
oversight was that PlatformMacOSX (despite the name) is active for any native
Darwin operating system, where lldb and the target process are running on the
same system. This patch uses compile-time checks to return the appropriate
OSType for the OS lldb is being compiled to, so the "host" platform will
correctly be selected when lldb & the inferior are both running on that OS.
And a small change to PlatformMacOSX::GetSupportedArchitectures which adds
additional recognized triples when running on macOS but not other native Darwin
systems.
When PlatformMacOSX is compiled on a non-Darwin system where we don't have
these availability macros, we will continue to return macOS as the OSType, as
we were before.
