tools lib traceevent: Use global QUIET_LINK build output

Using global QUIET_LINK build output variable and getting rid of local
print_static_lib_build, print_plugin_build and print_shared_lib_compile.

We no longer distinguish between shared and static library in the build
message. It's differenced by the built file suffix, like:

  $ make
    ...
    LINK     libtraceevent.a
    LINK     libtraceevent.so
