    procfs: mark thread stack correctly in proc/<pid>/maps

This patch still breaks nommu builds. The previous syntax issue has been
resolved, but now I see a link error:

fs/built-in.o: In function `nommu_vma_show':
task_nommu.c:(.text+0x564a0): undefined reference to `vm_is_stack'
make[1]: *** [.tmp_vmlinux1] Error 1
