IMPALA-3677: Write minidump on SIGUSR1

Sending SIGUSR1 to any of the impala daemons (catalogd, impalad,
statestored) will trigger a minidump write.

The hotspot JVM also uses SIGUSR1 internally. However the documentation
explains, that existing signal handlers will be transparently wrapped by
the JVM and no spurious signals should be received by the daemon signal
handler:

Example: killall -SIGUSR1 catalogd
