Mostly, you can do ./testrun.sh support/test-container ./some-program

There's overhead in $srcdir/Rules to handle all the other environment
variables needed for various tests, but you have that as a manual step
the old way too.

Otherwise, if you happen to be running a test with a container setup,
it autodetects that.  So this should work:

$ ./testrun.sh support/test-container nss/tst-nss-test3

where it finds nss/tst-nss-test3/* and sets up the container for you.
