Move headers around to fix issues on custom-built glibc

restorer.h eventually includes fcntl-linux.h system file, which
indiscriminately defines F_SETPIPE_SZ/F_GETPIPE_SZ. But those
are also defined by CRIU's own headers in config-base.h. The latter
contains ifdef guards, however in arch/x86/crtools.c it's included
after restorer.h which causes gcc warnings for macro redefinition.

Fix this by reordering the 2 headers, ensuring the ifdef guards in
config-base.h actually work.
