[completion] Allow ignores for '/etc/hosts' entries to be dynamic

Browse Source 
By keeping the variable `_etc_host_ignores` around, it can be resolved
lazily which is turn should allow selective ignores on a per invocation
basis.

Also, `'\#'` doesn't need to be added to `_etc_host_ignores` anymore.
It is enforced inline.
