[OE-core] [PATCH] util-linux: split libraries dynamically

[Ross Burton]

util-linux has a number of utility libraries and not noticing a new one being
added in an upgrade results in many of the split-out core tools depending on the
entire package for the library.  To prevent this happening in the future do the
library packaging dynamically.

As a side-effect libsmartcols.so is no longer packaged in util-linux so
util-linux-fdisk no longer depends on the full util-linux.
