[gdb/testsuite] Remove superfluous 3rd argument from gdb_test call (4)

There's a pattern:
...
gdb_test <command> <pattern> <command>
...
that can be written shorter as:
...
gdb_test <command> <pattern>
...

Detect this pattern in proc gdb_test:
...
     global gdb_prompt
     upvar timeout timeout

     if [llength $args]>2 then {
        set message [lindex $args 2]
+       if { $message == [lindex $args 0] && [llength $args] == 3 } {
+           error "HERE"
+       }
     } else {
         set message [lindex $args 0]
     }
...
and fix all occurrences in the testsuite/gdb.base subdir.

Tested on x86_64-linux.
