util: Use meson checks for valloc() and memalign() presence
Instead of assuming that all CONFIG_BSD have valloc() and anything else is memalign(), explicitly check for those functions in meson.build and use the "is the function present" define. Tests for specific functionality are better than which-OS checks; this also lets us give a helpful error message if somehow there's no usable function present.
