Remove old lint from PRODUCT_PACKAGES

There was no module named lint, so the entry was ignored.  Adding a
new host module named lint triggers an error:
build/make/core/main.mk:1293: warning:  Host modules should be in PRODUCT_HOST_PACKAGES, not PRODUCT_PACKAGES
Offending entries:
lint

Remove the old entry.

Test: lunch mini_armv7a_neon-eng && m nothing
