[PATCH 08/18] trace-cmd: Move libtracecmd *.c files in lib/trace-cmd

[Vladislav Valtchev (VMware)]

This patch moves all the source files belonging to the trace-cmd library into
the dedicated directory lib/trace-cmd. The build system has been updated to
support this new directory structure by adding a dedicated Makefile in
lib/trace-cmd and by making the parent Makefile to invoke it.
