net_template.py: Fix jinja2 template file search path (#15134)

Browse source 
The change is needed to support the multiple include statements
inside the jinja2 template file, as in '{% include ['another.j2'] %}'.
statement.  I need this capability, as OpenSwitch `switch` role needs
to handle multiple *.j2 files and supporting the include statement
inside jinja2 file is essential, otherwise I need to combine multiple
template files into a single file, which easily causes conflicts
between developers working on different parts of the teamplate, ports
and interface.
