f2fs-tools: add library version info

Browse Source 
This patch gives the version info for two libraries.

mkfs/libf2fs_format.la
lib/libf2fs.la

The versioning rule should be:

1. Start with version information of '0:0:0' for each libtool library.
2. Update the version information only immediately before a public release of
   your software. More frequent updates are unnecessary, and only guarantee
   that the current interface number gets larger faster.
2. If the library source code has changed at all since the last update, then
   increment revision (c:r:a) becomes (c:r+1:a).
3. If any interfaces have been added, removed, or changed since the last update,
   increment current, and set revision to 0.
4. If any interfaces have been added since the last public release, then
   increment age.
5. If any interfaces have been removed or changed since the last public release,
   then set age to 0.
