Make CMakeLists.txt discover if mbed TLS is being built as subproject

Browse source 
The main CMakeLists.txt is capable to detect if it's being built as
a subproject (i.e. through add_subdirectory()) hence allowing to
disable the package configuration, target export and installation
that generally are not required when mbed TLS is being built as
part of another project.
