perf dlfilter: Amend documentation wrt library dependencies



Like all locally-built programs, dlfilters may need to be re-built if
shared libraries they use change. Also there may be unexpected results
if the dfilter uses different versions of the shared libraries that perf
uses.

Note those things in the documentation.

		NOTES
		-----

		The dlfilter .so file will be dependent on shared libraries. If those change,
		it may be necessary to rebuild the .so. Also there may be unexpected results
		if the .so uses different versions of the shared libraries that perf uses.
		Versions can be checked using the ldd command.
