    gdb: testsuite: fix failed testcases in gdb.base/gdb-caching-proc.exp
    
    When execute the following command:
    
      make check-gdb TESTS="gdb.base/gdb-caching-proc.exp"
    
    we can see there exist some failed testcases:
    
      FAIL: gdb.base/gdb-caching-proc.exp: can_spawn_for_attach: 0: can spawn for attach (got interactive prompt)
      FAIL: gdb.base/gdb-caching-proc.exp: can_spawn_for_attach: 1: can spawn for attach (got interactive prompt)
      FAIL: gdb.base/gdb-caching-proc.exp: can_spawn_for_attach: 2: can spawn for attach (got interactive prompt)
      FAIL: gdb.base/gdb-caching-proc.exp: can_spawn_for_attach: 3: can spawn for attach (got interactive prompt)
      FAIL: gdb.base/gdb-caching-proc.exp: can_spawn_for_attach: 4: can spawn for attach (got interactive prompt)
      FAIL: gdb.base/gdb-caching-proc.exp: can_spawn_for_attach: 5: can spawn for attach (got interactive prompt)
      FAIL: gdb.base/gdb-caching-proc.exp: can_spawn_for_attach: 6: can spawn for attach (got interactive prompt)
      FAIL: gdb.base/gdb-caching-proc.exp: can_spawn_for_attach: 7: can spawn for attach (got interactive prompt)
      FAIL: gdb.base/gdb-caching-proc.exp: can_spawn_for_attach: 8: can spawn for attach (got interactive prompt)
      FAIL: gdb.base/gdb-caching-proc.exp: can_spawn_for_attach: 9: can spawn for attach (got interactive prompt)
    
    here are the detailed messages in gdb/testsuite/gdb.log:
    
      attach 873776
      A program is being debugged already.  Kill it? (y or n) n
      Not killed.
      (gdb) FAIL: gdb.base/gdb-caching-proc.exp: can_spawn_for_attach: 0: can spawn for attach (got interactive prompt)
    
    so handle the case "A program is being debugged already.  Kill it" in
    can_spawn_for_attach to fix the failed testcases.
