[PATCH 1/2] trace-cmd: add install_libs target to trace-cmd

[Josef Bacik]

I'd like to be able to build and link against libtracecmd, so add a make target
to build libtracecmd and install it into lib as well as the supporting header
files.  This allows me to be able to make stand alone apps that build and link
against trace-cmd for custom trace tools that don't have a place in the generic
trace-cmd tool.  Thanks,
