meson: be strict for boolean options

While Meson buildsystem accepts the 'false' as a value
for boolean options, it's not covered by the specification
and in general invalid. Some alternative Meson implementations,
like Muon, do not accept 'false' or 'true' as a valid value
for the boolean options.
