tests: replace test_tristate with "git env--helper"
The test_tristate helper introduced in 83d842dc8c ("tests: turn on network daemon tests by default", 2014-02-10) can now be better implemented with "git env--helper" to give the variables in question the standard boolean behavior. The reason for the "tristate" was to have all of false/true/auto, where "auto" meant either "false" or "true" depending on what the fallback was. With the --default option to "git env--helper" we can simply have e.g. GIT_TEST_HTTPD where we know if it's true because the user asked explicitly ("true"), or true implicitly ("auto"). This breaks backwards compatibility for explicitly setting "auto" for these variables, but I don't think anyone cares. That was always intended to be internal. This means the test_normalize_bool() code in test-lib-functions.sh goes away in addition to test_tristate(). We still need the test_skip_or_die() helper, but now it takes the variable name instead of the value, and uses "git env--bool" to distinguish a default "true" from an explicit "true" (in those "explicit true" cases we want to fail the test in question).
