qemu/boards: Exclude Thumb2 tests and tests failing with native emitter.

The `asmbcc`, `asmbitops`, `asmconst` and `asmit` tests fail to compile
with mpy-cross on armv6 architecture (used by SABRELITE), so explicitly
exclude them.

The `math_domain` and `vfs_rom` tests fail when compiled to native machine
code, so also exclude those unconditionally.
