package/openzwave: fix strncat build failure

Retrieve upstream patch that fixes a build failure caused by
strncat():

error: 'char* strncat(char*, const char*, size_t)' output may be truncated copying between 0 and 253 bytes from a string of length 253

This patch also allow to disable the use of the bundled tinyxml
library so use this new option and add a dependency of openzwave on
tinyxml to use it as a regular external library.
