linux-user/main: Suppress out-of-range comparison warning for clang

Browse Source 
For arm32 host and arm64 guest we get

.../main.c:851:32: error: result of comparison of constant 70368744177664 with expression of type 'unsigned long' is always false [-Werror,-Wtautological-constant-out-of-range-compare]
        if (TASK_UNMAPPED_BASE < reserved_va) {
            ~~~~~~~~~~~~~~~~~~ ^ ~~~~~~~~~~~

We already disable -Wtype-limits here, for this exact comparison, but
that is not enough for clang.  Disable -Wtautological-compare as well,
which is a superset.  GCC ignores the unknown warning flag.
