* proccess_collector: add wasip1 stub
This resolves build failures like this when using the wasip1 support:
# github.com/prometheus/procfs
../../../go/pkg/mod/github.com/prometheus/procfs@v0.11.1/fs_statfs_type.go:25:18: undefined: syscall.Statfs_t
../../../go/pkg/mod/github.com/prometheus/procfs@v0.11.1/fs_statfs_type.go:26:17: undefined: syscall.Statfs
See https://go.dev/blog/wasi.
