simplify lua dependency lookup

Barnabás Pőcze requested to merge pobrn/wireplumber:simplify_dep_lookup into master
The `dependency()` function can accept multiple dependency
names since meson 0.60.0, so increase the required meson
version and use this feature. For consistency, "lua53" is
added to the list of dependency names. Meson 0.60.0 was
released exactly a year ago and is available in recent
releases of many distributions.
