[patch] no output when executing md5sum in back quotes

[Daniel Farrugia]

Hello List,

The md5sum applet included with busybox 1.5.0 seems to have a problem
when executed inside back quotes. Running the applet directly from the
shell works fine however when back quotes are used there is no output:

% busybox md5sum busybox            [works]
% echo `busybox md5sum busybox`     [no ouput]

It seems that the applet doesn't flush stdout before exiting. The
trivial patch included below fixed this problem for me.

Thanks and Regards,
Daniel Farrugia
