In order to clean up the directory structure, move the features.mk into the
scripts directory. That's where the helper files for the Makefile should
live anyway.

Remove the variable LIBTRACEFS_DIR as it is simply bdir, and makes the
Makefile confusing. Simply use $(bdir) where $(LIBTRACEFS_DIR) is currently
used.

The macros LIBTRACEFS_STATIC is defined as $(bdir)/libtracefs.a and
LIBTRACEFS_SHARED is defined as $(bdir)/libtracefs.so.$(TRACE_VERSION).
Instead of open coding them elsewhere in the file, simply use the defined
macros.

As libtracefs is dependent on libtraceevent, use the proper pkg-config
method to find where libtraceevent is installed.

"make clean" was leaving behind libtracefs.so.0, in the lib/tracefs
directory. Add $(bdir)/*.so.* to the remove line to catch these files as
well.
