    rust: Update usage of TARGET_AIX to TARGET_AIX_OS
    
    This was noticed when fixing the gccgo usage of the macro, the
    rust usage is very similar.
    
    TARGET_AIX is defined as a non-zero value on linux/powerpc64le
    which may cause unexpected behavior.  TARGET_AIX_OS should be
    used to toggle AIX specific behavior.

    gcc/rust/
            * rust-object-export.cc [TARGET_AIX]: Rename and update usage to
            TARGET_AIX_OS.
    
    (cherry picked from commit 8a30775b0d3037123ee540f7b65a736ad49e05ce)
