[PATCH] android/client: Fix annoying delay in command line

[Jerzy Kasenberg <jerzy.kasenberg@tieto.com>]

Move fflush(stdout) to after prints and user input.
This removes delay of showing prompt.
---
Same effect could be achieved by calling setbuf(stdout, NULL)
in terminal_setup() then all fflush calls could be removed.

If you think this should be better approach, I will change it.
