arm64: debug: report TRAP_TRACE instead of TRAP_HWBRPT for singlestep

Single-step traps to userspace (e.g. via ptrace) are expected to use
the TRAP_TRACE for the si_code field of the siginfo, as opposed to
TRAP_HWBRPT that we report currently.

Fix the reported value, which has no effect on existing and legacy
builds of GDB.
