meson: use better check for debug builds

meson 0.48 added the 'debug' and 'optimization' builtin options, which
bidirectionally map to the buildtype, but in some cases where debug is
enabled, the builtype may be custom. Checking the 'debug' option lets us
detect every case currently detected, plus a few more, and does so in a
shorter and more concise manner.
