jansson: revert ABI version bump

The soversion of the shipped libjansson.so library didn't change, so the
ABI version change is unwarranted and leads to opkg file clashes.

Also stop shipping an unversioned library symlink while we're at it as
it only needed at compile/link time and leading to file level clashes
between packages on future ABI bumps.
