eslint: avoid dev dependencies to reduce closure size

Browse source 
Omitting npm dev dependencies reduces eslint closure size significantly.
This is helpful when using eslint in build pipelines. Following numbers
from `nix path-info --size --closure-size --human-readable` on
aarch64-darwin.

size of:    eslint    closure  remark:
before:  438.3 MiB    2.7 GiB  (includes apple-sdk, compiler, etc.)
after:    10.6 MiB  202.1 MiB  (npmInstallFlags --omit=dev)
