[PATCH] tools lib traceevent: Add dependency to libdl

[Namhyung Kim]

The libtraceevent has dependency to libdl due to plugins.  So if
external program wants to link libtraceevent it also needs to add -ldl
to the compiler command line.  Make it explicit so that external
programs doesn't care about the internel dependency of libtraceevent
anymore.
