Collect hs_err_pid*.log files in logs/

These JVM error dumps are often useful for debugging job failures. We
should put them into the logs/ directory so they can be collected
along with other logs.

This was motivated by IMPALA-7069.

Testing:
Induced a segfault by changing the code, checked that the file ended up
in the logs/ subdirectory.
