IMPALA-14000: Dump jstacks first in dump-stacktraces.sh

Browse Source 
bin/dump-stacktraces.sh collects pstack and jstack of the cluster. It's
used when some tests time out. Collecting pstacks might take long and
fail in the middle, causing jstacks not being collected. This changes
the script to collect jstacks first.

Also adds -c to the "thread apply all bt" gdb command to continue past
an error.
