ParseXS: standard_typemap_locations(): rm cache

standard_typemap_locations() has a static variable, @tm_template,
which it populates with all the '../../typemap' etc paths on first call,
then reuses on subsequent calls.

This doesn't seem very useful, since standard_typemap_locations() is
typically only called once per run of xsubpp etc. And anyway,
regenerating those paths (which doesn't involve any IO) isn't costly. So
simplify the code by removing the cache.
