[PATCH] selftests: breakpoints: fix compile error on breakpoint_test_arm64

[Sumit Semwal]

The current mainline breakpoints test for arm64 fails to compile with

breakpoint_test_arm64.c: In function âset_watchpointâ:
breakpoint_test_arm64.c:97:28: error: storage size of âdreg_stateâ isnât known
  struct user_hwdebug_state dreg_state;

Adding a direct include for asm/ptrace.h helps it to build, and passes
the test on mainline on hikey.
