HID: bpf: Make syscall kfunc flags match the struct_ops set
Update kfunc flags for hid_bpf_syscall_kfunc_ids set to exactly match
hid_bpf_kfunc_ids set by adding KF_SLEEPABLE flag.
The syscall set omitted the flag because syscall programs are always
sleepable (the verifier rejects a non-sleepable syscall program).
However the upcoming resolve_btfids change enforces per-kfunc flag
consistency across BTF ID sets at build time, which is why this change
is necessary.
