[PATCH 2/2] rust: update usage of TARGET_AIX to TARGET_AIX_OS

[Paul E. Murphy via Gcc-patches]

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/ChangeLog:

        * rust-object-export.cc [TARGET_AIX]: Rename and update
        usage to TARGET_AIX_OS.
