functions/__fish_print_hostnames: Fix ssh_configs no values return (#6236)

Browse source 
* functions/__fish_print_hostnames: Fix ssh_configs no values return
`string replace` not working with mutlilines variable.
So split per line first.

* functions/__fish_print_hostnames: remove quotes at `split '\n'`
"\n with quotes" will cause `string split` weird issues.

* functions/__fish_print_hostnames: using `read -alz -d \n`
Fix `$contents` issues together
