perf/bpf: fix a clang compilation issue
clang does not support variable length array for structure member.
It has the following error during compilation:
kernel/trace/trace_syscalls.c:568:17: error: fields must have a constant size:
'variable length array in structure' extension will never be supported
unsigned long args[sys_data->nb_args];
^
The fix is to use a fixed array length instead.
