[libvirt PATCH 1/2] ci: Fix precedence between arguments passed to meson

[Andrea Bolognani]

Commit 9c9848f955fd merged $MESON_OPTS into $MESON_ARGS, and
while doing so changed their behavior: while until then the
contents of $MESON_ARGS had precedence over those of $MESON_OPTS,
now the opposite is true. Restore the original behavior and
document it.

The argument for merging the two variables in the first place
was that having both present on the meson command line could be
confusing; however, that should no longer be the case now that
we have reasonably extensive comments explaining the role of
each of the variables and how they interact with each other, so
return the meson command line to its original form.
