libcrc32c: Fix "crc32c undefined" compilation error
The latest shash changes leave crc32c undefined:
[...]
Building modules, stage 2.
MODPOST 1381 modules
ERROR: "crc32c" [net/sctp/sctp.ko] undefined!
ERROR: "crc32c" [net/ipv4/netfilter/nf_nat_proto_sctp.ko] undefined!
Adding EXPORT_SYMBOL(crc32c) to lib/libcrc32c.c fixes the compile error.
This patch has been compile-tested only.
