[PATCH] gdb, testsuite: increase timeout in gdb.threads/attach-non-stop.exp

[Markus Metzger <markus.t.metzger@intel.com>]

Attaching sporadically timed out on my system while reading symbols...

    FAIL: gdb.threads/attach-non-stop.exp: target-non-stop=off: non-stop=on: cmd=attach: attach (timeout)

Adjust the timeout to avoid sporadic fails.
