docs: Remove unused weirdly-named cross-reference targets

In the doc sources, we have a few cross-reference targets with odd
names "pcsys_005fxyz".  These are the legacy of the semi-automated
conversion of the old info docs to rST (the '005f' is because ASCII
0x5f is '_' and the old info link names had underscores in them).

Remove the targets which nothing links to, and rename the two targets
which are used to something a bit more descriptive.

=========
Using igb should be nothing different from using another network device. See
:ref:`pcsys_005fnetwork` in general.
:ref:`Network_emulation` in general.
However, you may also need to perform additional steps to activate SR-IOV
feature on your guest. For Linux, refer to [4]_.
