lib/Makefile: make union-find compilation conditional on CONFIG_CPUSETS
Currently, cpuset is the only user of the union-find implementation.
Compiling union-find in all configurations unnecessarily increases the
code size when building the kernel without cgroup support. Modify the
build system to compile union-find only when CONFIG_CPUSETS is enabled.
