Search another path for etc/tempest

sys.prefix is gotten from the path which pyconfig.h is installed under.
Some envs contain it under /usr/include, not /user/local/include.
Then prefix becomes /usr on such envs.
However, etc/tempest is installed under /usr/local and the original
path logic mismatches.

This patch adds a workaround for such envs.
