[PATCH 03/29] gdb/testsuite: Remove duplicates from gdb.base/interp.exp

[Lancelot SIX]

When running the testsuite I have:

    Running .../gdb/testsuite/gdb.base/interp.exp ...
    DUPLICATE: gdb.base/interp.exp: interpreter-exec mi "-var-update *"

This is due to the fact that two successive instances of
gdb_test_multiple use 'pass $cmd', but the second test forgets to reset
$cmd.

Fix by updating the value of cmd where appropriate.

Tested on x86_64-linux.
