Extend include path in *.pc file (#319)

* Extend include path in *.pc file

Previously, an application using this library's pkg-config setting for
include directory would only get e.g. -I/usr/local/dlt/include/dlt
With that include dir, the application needs to write its #include
statements without any prefix, i.e. "#include "dlt_user.h"

This is considered bad practice for header files of an elaborate
library consisting of multiple header files.
For such libraries, one should write #include statements like
this: #include "dlt/dlt_user.h", i.e. prefix it with a directory.

This commit achieves that by letting the pkg-config module also return
the upper-level directory in addition to the previous one.
For instance, the include directive returned by the above example
would now be "-I/usr/local/dlt/include -I/usr/local/dlt".
