[PATCH 1/7] fdisk: stop buffering welcome message

[Davidlohr Bueso <dave@gnu.org>]

From: Davidlohr Bueso <dave@gnu.org>

Recently, commit 0a86755fe8af1da510d2eca43bdfcd70af098c19 directed the welcome message output from stderr to stdout breaking regression tests.
Correct this by flushing stdout and stop buffering the output - a trivial function is created as well.
