Linking 'btrfs' and other binaries against the dynamic library makes it
tedious to use directly from the git repo. This is useful for testing
various fixes, but now it'd need to also set LD_LIBRARY_PATH or install
the library to a known path.
Add a target for static library and use it for linking, the dynamic
library is to be used by external users.
