[PULL 1/1] linux-user: don't print core dump message by default

[Helge Deller <deller@kernel.org>]

From: Andreas Schwab <schwab@suse.de>

When the target binary is killed by a signal with core dump print a
message to the guest_errors log instead of stderr.  This avoids breaking
various testsuites due to the extra output produced by the emulation.
