Also search config.h near the script

Browse Source 
By default, this script looks for include/mbedtls/config.h relative to
the current directory. This allows running config.py from outside the
build tree.

To support out-of-tree builds where config.h and config.py are in the
source tree and the current directory is in the build tree, also try
DIRECTORY_CONTAINING_SCRIPT/../include/mbedtls/config.h, and the
equivalent with symbolic links traversed.
