lib: use flag from new libyang version to simplify the code

Browse Source 
When using the LYD_PATH_OPT_NOPARENTRET flag, lyd_new_path() returns
the path-referenced node instead of the first created node. This
flag wasn't available in libyang 0.16-r1 so we couldn't use it
before. Use it now to simplify the code where possible.
