Bug #5829 mysqlimport garbles path of the file to be imported

Original code was checking ! unix_socket for local_file flag.  This doesn't work and so was removed.  Now
to import a local file, you must use the --local command line option.

mysqlimport.c:
  Removed check of unix_socket to set local_file
