conf: Use LFS calls when reading config files

Browse source 
Although at first glance it doesn't seem useful to support config
files larger than 2GB, LFS also influences inode size. Without this,
32-bit libasound may be unable to read config files on filesystems
with 64-bit inodes, such as Btrfs or NFS.
