Ports/python3: Make pip work

Add two patches to allow Python's package manager to work on Serenity:

- The first one enables zlib module, which is needed for `ensurepip`
  command;
- The second patch fixes pip downloads, so it's possible to install
  packages from the PyPI repository.

+Subject: [PATCH] Workaround for unsupported socket option
+
+This is a workaround for ignoring the result of `setsockopt` call when
+given `TCP_NODELAY` as an argument. This TCP socket option is used in
+many applications (like pip and requests) for optimization purposes.
+For now, it can be safely ignored until it's supported in the kernel.
