OS400/EBCDIC Port: Implement apr_file_mtime_set() alternative.

This is one of several patches to allow Subversion to run on IBM's
OS400 V5R4.  It uses the OS400 specific function apr_utime() instead
of apr_file_mtime_set(), which is not implemented on OS400 APR.

* subversion/libsvn_subr/io.c
   (svn_io_set_file_affected_time): Use apr_utime() to set file
    modification time.
