Mahmoud Al-Qudsi 912421f1cb Switch away from awk for __fish_print_hostnames
By not manipulating each line or even each file at a time, we can go
back to `string` and piece together a pipeline that will execute
significantly faster than shelling out to `awk` will. This also removes
one of the few dependencies on `awk` in the codebase.

With this change, `__fish_print_hostnames` now finishes ~80% faster than
it used to a few commits back.
