[bash] statically define __fzf_list_hosts() with either method
When bash-completion (and thus `_known_hosts_real()`) is / is not available this
will typically not change during the lifetime of a shell.
The only exception is if the user would unset `_known_hosts_real()`, but well,
that would be his problem.
So we can easily define `__fzf_list_hosts()` either using `_known_hosts_real()`
or using the old code, and avoid checking every time whether
`_known_hosts_real()` is defined.
