Alex Bennée 542b10bd14 tests/tcg: update licenses to GPLv2 as intended
My default header template is GPLv3 but for QEMU code we really should
stick to GPLv2-or-later (allowing others to up-license it if they
wish). While this is test code we should still be consistent on the
source distribution.

I wrote all of this code so its not a problem. However there remains
one GPLv3 file left which is the crt0-tc2x.S for TriCore.
