btrfs: Fix build error while LIBCRC32C is module

If CONFIG_BTRFS_FS is y and CONFIG_LIBCRC32C is m,
building fails:

  fs/btrfs/super.o: In function `btrfs_mount_root':
  super.c:(.text+0xb7f9): undefined reference to `crc32c_impl'
  fs/btrfs/super.o: In function `init_btrfs_fs':
  super.c:(.init.text+0x3465): undefined reference to `crc32c_impl'
  fs/btrfs/extent-tree.o: In function `hash_extent_data_ref':
  extent-tree.c:(.text+0xe60): undefined reference to `crc32c'
  extent-tree.c:(.text+0xe78): undefined reference to `crc32c'
  extent-tree.c:(.text+0xe8b): undefined reference to `crc32c'
  fs/btrfs/dir-item.o: In function `btrfs_insert_xattr_item':
  dir-item.c:(.text+0x291): undefined reference to `crc32c'
  fs/btrfs/dir-item.o: In function `btrfs_insert_dir_item':
  dir-item.c:(.text+0x429): undefined reference to `crc32c'

Select LIBCRC32C to fix it.
