[PULL 30/45] docs: set CONFDIR when running sphinx

[Paolo Bonzini]

From: Marc-André Lureau <marcandre.lureau@redhat.com>

The default configuration path /etc/qemu can be overriden with configure
options, and the generated documentation used to reflect it.

Fixes regression introduced in commit
f8aa24ea9a82da38370470c6bc0eaa393999edfe ("meson: sphinx-build").
