selftests/futex: don't pass a const char* to asprintf(3)
When building with clang, via:
make LLVM=1 -C tools/testing/selftests
...clang issues this warning:
futex_requeue_pi.c:403:17: warning: passing 'const char **' to parameter
of type 'char **' discards qualifiers in nested pointer types
[-Wincompatible-pointer-types-discards-qualifiers]
This warning fires because test_name is passed into asprintf(3), which
then changes it.
Fix this by simply removing the const qualifier. This is a local
automatic variable in a very short function, so there is not much need
to use the compiler to enforce const-ness at this scope.
