[netdump] Minor refactoring of packet filter

Some minor tidy-up to the packet filter code:
- Refactoring out of constants from the filter implementation, so the
  lexer and parser components do not depend on the filter header.
- Linting of some method signatures in lexer.

Bug: CONN-99
Test: Build with `--with-base //garnet/packages/tests:zircon` as a
parameter to `fx set`, then `runtests -t netdump-test` on the target.
This CL does not change any observable behavior.
