[PATCH] tests: enable Automake parallel testsuite harness

It is better than the older test driver.  It is also the default now,
starting from Automake 1.13; so having it enabled unconditionally will
allow GNU sed to be seamlessly bootstrapped by Automake 1.13.

* configure.ac (AM_INIT_AUTOMAKE): Add 'parallel-tests' option.  Also
require Automake 1.11.1, since that is the minimal version to have a
sane 'parallel-tests' support.
(AC_PREREQ): Bump requirement to 2.62, since that is the minimal
version required by Automake 1.11.1.
* testsuite/Makefile.am (TESTS_ENVIRONMENT): Remove the invocation
for the test runner "$(srcdir)/runtest"; it's correct place is ...
(LOG_COMPILER): ... here.
