[PULL 1/7] linux-user/aarch64: Set siginfo_t addr field for SIGTRAP signals

[Laurent Vivier]

From: Peter Maydell <peter.maydell@linaro.org>

When generating a TRAP_BRKPT SIGTRAP, set the siginfo_t addr field
to the PC where the breakpoint/singlestep trap occurred; this is
what the kernel does for this signal for this architecture.
