glcpp: Fix locations when encounting "#<NEWLINE>".

We were failing to reset our location tracking when encountering a
NEWLINE in the <HASH> state.  Rip the code from the <*>{NEWLINE} rule,
which handles this properly.

Also, update 146-version-first-hash.c to have proper expectations.
When I introduced the test, I didn't verify that the line/column
numbers were correct, and it turns out they varied based on the type
of newline ending.
