[PATCH] acl-tests: fix AIX 7.3 aclx_* constness

* tests/test-sameacls.c (main): AIX 7.3’s aclx_* APIs want char *
parameters, not char const *.  Change arguments accordingly.  This
pacifies IBM Open XL C/C++ for AIX 17.1.1 (5725-C72, 5765-J18),
version 17.1.1.2, clang version 15.0.0 (build 3948f09) with
-Wincompatible-pointer-types-discards-qualifiers.
