[PULL 01/22] scripts/kernel-doc: strip QEMU_ from function definitions

Some packaged versions of Sphinx (fedora33/alpine so far) have issues
with the annotated C code that kernel-doc spits out. Without knowing
about things like QEMU_PLUGIN_EXPORT it chokes trying to understand
the code. Evidently this is a problem for the kernel as well as the
long stream of regex substitutions we add to in this patch can attest.

Fortunately we have a fairly common format for all our compiler
shenanigans as applied to functions so lets just filter them all out.
