ARM: stacktrace: include asm/sections.h in asm/stacktrace.h

The recent kstack erase changes appear to have uncovered an existing
issue with a missing header inclusion:

In file included from drivers/misc/lkdtm/kstack_erase.c:12:
In file included from include/linux/kstack_erase.h:16:
arch/arm/include/asm/stacktrace.h:48:21: error: call to undeclared function 'in_entry_text'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
   48 |                 frame->ex_frame = in_entry_text(frame->pc);
      |                                   ^

Include asm/sections.h here so the compiler can see the in_entry_text()
declaration.
