fix: elb macOS OpenSSL + C master declarations header; add ELP missing imports

elb.el:
- Auto-detect Homebrew OpenSSL (-L$(brew --prefix openssl)/lib) so -lssl
  resolves on macOS without manual flags; no-op on Linux
- Add -include elp-c-decls.h when present in out_dir: resolves undeclared
  cross-module calls in packages like ELP that lack explicit imports

ELP source:
- Add import "morphology.el" to all 29 language morphology modules
- Add language module imports to morphology.el (all langs it dispatches to)
  These were missing since ELP was originally built as a monolithic unit

elp/src/morphology-ja.el
