    [gdb/testsuite] Fix -prompt handling in gdb_test
    
    With check-read1 I run into:
    ...
       [infrun] maybe_set_commit_resumed_all_targets: not requesting
    commit-resumed for target native, no resumed threads^M
    (gdb) FAIL: gdb.base/ui-redirect.exp: debugging: continue
    [infrun] fetch_inferior_event: exit^M
    ...
    
    The problem is that proc gdb_test doesn't pass down the -prompt option to proc
    gdb_test_multiple, due to a typo making this lappend without effect:
    ...
        set opts {}
        lappend "-prompt $prompt"
    ...
    
    Fix this by actually appending to opts.
    
    Tested on x86_64-linux.
