[PATCH v3 2/3] linux-user: Exit not abort in die_with_backtrace

[Richard Henderson <richard.henderson@linaro.org>]

This line is supposed to be unreachable, but if we're going to
have it at all, SIGABRT via abort() is subject to the same signal
peril that created this function in the first place.

We can _exit immediately without peril.
