There's a cyclic dependency on siderolink library which imports talos
machinery back. We will fix that after we get talos pushed under a new
name.

As `talosctl time` relies on default time server set in the config, and
our nodes start with `pool.ntp.org`, sometimes request to the timeserver
fails failing the tests.
Retry such errors in the tests to avoid spurious failures.

Fixes#4688
Instead of using generic library, build some handcrafted code to
reuse buffers, do partial parsing of the data we need for the processes
API.
Benchmark (it runs with significant number of processes on the host):
```
name time/op
PrometheusProcfs-16 3.42ms ± 8%
Processes-16 2.36ms ± 5%
name alloc/op
PrometheusProcfs-16 366kB ± 0%
Processes-16 255kB ± 0%
name allocs/op
PrometheusProcfs-16 6.76k ± 0%
Processes-16 3.83k ± 0%
```
