Fabian Boehm b31387416d Optimize fish_config theme choose

Just following basic shellscript optimization:

- Remove a useless use of cat (`status get-file` takes microseconds,
`status get-file | cat` is on the order of a millisecond - slower with
bigger $PATH)
- Pipe, don't run in a loop
- Filter early

This reduces the time taken from 12ms to 6ms on one of my systems, and
6.5ms to 4.5ms on another.

This is paid on every single shell startup, including
non-interactively, so it's worth it.

There's more to investigate, but this is a good first pass.
