gdb/csky add unwinder for sigtramp frame when kernel 4.x and later
When kernel veriosn >= V4.x, the characteristic values used to
determine whether it is a signal function call are:
movi r7, 139
trap 0
Registers are saved at (sp + CSKY_SIGINFO_OFFSET + CSKY_SIGINFO_SIZE
+ CSKY_UCONTEXT_SIGCONTEXT + CSKY_SIGCONTEXT_PT_REGS_TLS). The order
is described in csky_linux_rt_sigreturn_init_pt_regs.
