tests/docker: Use binaries for debian-tricore-cross

since binutils is pretty old, it fails our CI repeatedly during the
compilation of tricore-binutils. We created a precompiled version using
the debian docker image and download it instead of building it ourself.

We also updated the package to include a newer version of binutils, gcc,
and newlib. The default TriCore ISA version used by tricore-as changed
from the old version, so we have to specify it now. If we don't
'test_fadd' fails with 'unknown opcode'.

The new assembler also picks a new encoding in ld.h which fails the
'test_ld_h' test. We fix that by using the newest TriCore CPU for QEMU.

The old assembler accepted an extra ')' in 'test_imask'. The new one
does not, so lets remove it.
