[PATCH] gdb, testsuite: fix gdb.multi/remove-inferiors.exp for remote targets

[Tankut Baris Aktemur]

When running gdb.multi/remove-inferiors.exp with the native-gdbserver
board file, we see

  WARNING: Timed out waiting for EOF in server after monitor exit

Fix this by switching back to inferior 2 at the end of the test.

When running with native-extended-gdbserver, we see

  FAIL: gdb.multi/remove-inferiors.exp: runto: run to main

Fix this by setting remote exec-file before running to main.

After this patch, we see

  # of expected passes            10

for all three of default, native-gdbserver, native-extended-gdbserver
board files.
