Subject: [PATCH 1/2] allegro5: split outputs -> out, dev

This avoids referencing apple-sdk in the main output on macOS/Darwin,
which saves over a gigabyte of closure size on programs built with
Allegro 5.

Resolves #397472.

Subject: [PATCH 2/2] allegro5: add `fixDarwinDylibNames`

Allows Allegro-based programs on macOS/Darwin to locate the libraries
at runtime, without needing a wrapper to set `DYLD_LIBRARY_PATH`.
