libnfc-llcp: rename to libllcp and bump version

This package has been renamed upstream to libllcp. Also, the current
package we have in Buildroot fails to compile due to a version bump of
it's main dependence, libnfc. A version bump is required because this
package has been adapted upstream to work with libnfc-1.7.0-rc6.
