meson: create have_vhost_* variables
When using Meson options rather than config-host.h, the "when" clauses
have to be changed to if statements (which is not necessarily great,
though at least it highlights which parts of the build are per-target
and which are not).
Do that before moving vhost logic to meson.build, though for now
the variables are just based on config-host.mak data.
