Use functools.lru_cache with _getconftest_pathlist 

For pytest's own suite the `cache_info()` looks as follows:

    > session.config._getconftest_pathlist.cache_info()
    CacheInfo(hits=231, misses=19, maxsize=None, currsize=19)

While it does not really make a difference for me this might help with
larger test suites / the case mentioned in
https://github.com/pytest-dev/pytest/issues/2206#issuecomment-432623646.
