Subject: [PATCH] build: do not rely on automake's AM_TESTS_ENVIRONMENT

* tests/Makefile.am (TESTS_ENVIRONMENT): Rename from
AM_TESTS_ENVIRONMENT, since it is not honored in automake-1.11.3
after all.  This reverts commit v3.1-14-g2bd66d7.  For now, I'll
leave the following commit that made bootstrap.conf require 1.11.2.
Prompted by a report of test failure from Phillip Susi.
