libbtrfs: create all .so links

Browse Source 
There will be an unplanned update to libbtrfs (fixing send/receive
stream parsing and unaligned data access). The current ABI is frozen and
won't change but at least the patch level should change. Update the build
to create all links up to the major.minor.patch. Until now it was just
major.minor:

- libbtrfs.so       -> libbtrfs.so.0.1.2
- libbtrfs.so.0     -> libbtrfs.so.0.1.2
- libbtrfs.so.0.1   -> libbtrfs.so.0.1.2
- libbtrfs.so.0.1.2
