[CRIU] [PATCH] Rework fixup_aufs_vma_fd() for non-AUFS links

[Saied Kazemi]

Thanks Pavel.

Just a quick note that building a fresh clone as of commit f3bf749b2b fails
with this error:

bfd.c:128:2: error: implicit declaration of function ‘close_safe’
[-Werror=implicit-function-declaration]

So I added #include "util.h" to bfd.c.

I am curious why the build hasn't failed for anyone else!
