Fix qemu endless loop when raising a SIGSEGV/SIGBUS signal with gdbstub in user emulation
When a SIGSEGV signal is raised in user mode emulation the current
test to know whether the signal is sent by the kernel is wrong :

info->si_code == SI_KERNEL

according to /usr/include/bits/siginfo.h it should be

info->si_code > 0
