[CRIU] [PATCH 2/4] images: add syntax specifier to autofs.proto

[Tycho Andersen]

avoids:

[libprotobuf WARNING google/protobuf/compiler/parser.cc:547] No syntax specified for the proto file: autofs.proto. Please use 'syntax = "proto2";' or 'syntax = "proto3";' to specify a syntax version. (Defaulted to proto2 syntax.)
