selftests/bpf: Fix conflicts with built-in functions in bench_local_storage_create
The fork function in gcc is considered a built in function due to
being used by libgcov when building with gnu extensions.
Rename fork to sched_process_fork to prevent this conflict.
See details:
https://github.com/gcc-mirror/gcc/commit/d1c38823924506d389ca58d02926ace21bdf82fa
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82457
Fixes the following error:
In file included from progs/bench_local_storage_create.c:6:
progs/bench_local_storage_create.c:43:14: error: conflicting types for
built-in function 'fork'; expected 'int(void)'
[-Werror=builtin-declaration-mismatch]
43 | int BPF_PROG(fork, struct task_struct *parent, struct
task_struct *child)
| ^~~~
