linux-user: Drop deprecated -p option

Browse source

doesn't do anything except emit a warning. We are well past
our minimum deprecation period, so drop the option.

The ``-p`` option pretends to control the host page size. However,
it is not possible to change the host page size, and using the

The ``-p`` option pretends to control the host page size. However,
it is not possible to change the host page size; we stopped trying
to do anything with the option except print a warning from 9.0,
and now the option is removed entirely.
