Michael Brown 7c8fc2cae8 [linux] Fail at link time if building slirp.linux without libslirp ...

The iPXE build system is constructed for a standalone codebase with no
external dependencies, and does not have any equivalent of the
standard userspace ./configure script.  We currently check for the
ability to include slirp/libslirp.h and conditionalise portions of
linux_api.c on its presence.  The actual slirp driver code is built
unconditionally, as with all iPXE drivers.

This currently leads to a silent runtime failure if attempting to use
slirp.linux built on a system that was missing slirp/libslirp.h.

Convert this to a link-time failure by deliberately omitting the
relevant symbols from linux_api.c when slirp/libslirp.h is not
present.  This allows other builds (e.g. tap.linux or tests.linux) to
succeed: the link-time failure will occur only if the slirp driver is
included within the build target.
