perf bench futex: Fix build on musl + clang
When building with clang on a musl libc system, Alpine Linux, we end up
hitting a problem where memset() is used but its prototype is not
present, add it to avoid this:
bench/futex-wake.c:99:3: error: implicitly declaring library function 'memset' with type 'void *(void *, int, unsigned long)'
[-Werror,-Wimplicit-function-declaration]
CPU_ZERO(&cpu);
^
/usr/include/sched.h:127:23: note: expanded from macro 'CPU_ZERO'
#define CPU_ZERO(set) CPU_ZERO_S(sizeof(cpu_set_t),set)
^
/usr/include/sched.h:110:30: note: expanded from macro 'CPU_ZERO_S'
#define CPU_ZERO_S(size,set) memset(set,0,size)
^
bench/futex-wake.c:99:3: note: include the header <string.h> or explicitly provide a declaration for 'memset'
Found while updating my test build containers to build perf with clang in more
systems.
