[PATCH] gdb, testsuite: fix gdb.base/save-history.exp for native-extended-gdbserver

[Tankut Baris Aktemur <tankut.baris.aktemur@intel.com>]

When executed with the native-extended-gdbserver board file, we get

  FAIL: gdb.base/save-history.exp: check history contents

This is because the history file contains an extra line for the
command 'target extended-remote ...'.  To keep the test
straightforward, skip it if using the extended-remote target.
