On aarch64 CONFIG_ARCH_STACKWALK is not defined and
print_stack_trace is not available.

Replace print_stack_trace with an open-coded variant
using %pB introduced in Linux v2.6.38-6557-g0f77a8d37825

This also fixes the symbols lookup of stack_trace_save_tsk
using kallsyms at module init time over the use of
symbol_get.
