test,internal/testdir: don't set GOOS/GOARCH

Browse Source 
The test directory driver currently sets the GOOS/GOARCH environment
variables if they aren't set. This appears to be in service of a
single test, test/env.go, which was introduced in September 2008 along
with os.Getenv. It's not entirely clear what that test is even trying
to check, since runtime.GOOS isn't necessarily the same as $GOOS. We
keep the test around because golang.org/x/tools/go/ssa/interp uses it
as a test case, but we simplify the test and eliminate the need for
the driver to set GOOS/GOARCH.
