tools lib traceevent: Install libtraceevent.a into libdir

Before this patch, 'make install' installs libraries into bindir:

$ make install DESTDIR=./tree
INSTALL trace_plugins
INSTALL libtraceevent.a
INSTALL libtraceevent.so
$ find ./tree
./tree/
./tree/usr
./tree/usr/local
./tree/usr/local/bin
./tree/usr/local/bin/libtraceevent.a
./tree/usr/local/bin/libtraceevent.so
...

/usr/local/lib( or lib64) should be a better place.

This patch replaces 'bin' with libdir. For __LP64__ building, libraries
are installed to /usr/local/lib64. For other building, to
/usr/local/lib instead.

After applying this patch:

$ make install DESTDIR=./tree
INSTALL trace_plugins
INSTALL libtraceevent.a
INSTALL libtraceevent.so
$ find ./tree
./tree
./tree/usr
./tree/usr/local
./tree/usr/local/lib64
./tree/usr/local/lib64/libtraceevent.a
./tree/usr/local/lib64/traceevent
./tree/usr/local/lib64/traceevent/plugins
./tree/usr/local/lib64/traceevent/plugins/plugin_mac80211.so
./tree/usr/local/lib64/traceevent/plugins/plugin_hrtimer.so
...
./tree/usr/local/lib64/libtraceevent.so
