Josh Boyer b935a58dbf perf tools: Fix traceevent plugin path definitions 
The plugindir_SQ definition contains $(prefix) which is not needed as
the $(libdir) definition already contains prefix in it.  This leads to
the path including an extra prefix in it, e.g. /usr/usr/lib64.

The -DPLUGIN_DIR defintion includes DESTDIR.  This is incorrect, as it
sets the plugin search path to include the value of DESTDIR.  DESTDIR is
a mechanism to install in a non-standard location such as a chroot or an
RPM build root.  In the RPM case, this leads to the search path being
incorrect after the resulting RPM is installed (or in some cases an RPM
build failure).

Remove both of these unnecessary inclusions.
