    Fix gdb.threads/dlopen-libpthread.exp crash
    
    Following, commit
    
      6e774b13c3b81ac2599812adf058796948ce7e95 Make ftrace tests work with remote targets
    
    the test gdb.threads/dlopen-libpthread.exp started to fail with:
    
      ERROR: error copying "/home/emaisin/build/binutils-gdb/gdb/testsuite/gdb.threads/dlopen-libpthread.so": no such file or directory
    
    This is because the library path is not computed using
    standard_output_file, so we try to gdb_load_shlibs an unexisting file.
    
    gdb/testsuite/ChangeLog:
    
    	* gdb.threads/dlopen-libpthread.exp: Set binfile_lib using
    	standard_output_file.  Remove unused binfile variable.
