perf top: Remove needless malloc(0) call that triggers -Walloc-size
GCC 14 introduces a new -Walloc-size included in -Wextra which errors out
like:
builtin-top.c: In function ‘prompt_integer’:
builtin-top.c:360:21: error: allocation of insufficient size ‘0’ for
type ‘char’ with size ‘1’ [-Werror=alloc-size]
360 | char *buf = malloc(0), *p;
| ^~~~~~
Just set it to NULL, getline() will do the allocation.
