dtc: Don't use env(1) in testsuite

The run_tests.sh script currently invokes the testcase binaries via
env(1).  This behaviour is inherited from the libhugetlbfs testsuite
which uses this approach to easily set various configuration
environment variables in testcases.

We don't use that for dtc, and are unlikely to ever want to.
Therefore this patch removes that technique, which substantially
speeds up the testsuite.
