[PULL 5/7] tests/tcg: disable xtensa-linux-user again

["Alex Bennée" <alex.bennee@linaro.org>]

From: Paolo Bonzini <pbonzini@redhat.com>

The move from tests/tcg/configure.sh started enabling the container image
for xtensa-linux-user, which fails because the compiler does not have
the full set of headers.  The cause is the "xtensa*-softmmu)" case
in tests/tcg/configure.sh which became just "xtensa*)" in the new
probe_target_compiler shell function.  Look out for xtensa*-linux-user
and do not configure it.
