[Buildroot] [PATCH 1/1] dropbear: bump version to 0.50 and remove urandom config option

This patch bumps the dropbear version number to 0.50 (from 0.49). It also
removes the menu option for configuring to use /dev/urandom as source for
entropy. /dev/urandom is the default source in dropbear 0.50.

Also minor cleanups in the makefile.

-	  By default, dropbear uses the much more secure /dev/random.  If you
-	  are using a system lacking usable entropy sources, this could cause
-	  the dropbear ssh daemon to block forever waiting for entropy that
-	  will never arrive.  By making dropbear use /dev/urandom, you can
-	  prevent Dropbear from blocking while waiting on the random device.
-	  This could however significantly reduce the security of your ssh
-	  connections.  Make sure you know what you are doing if you enable
-	  this option -- most people should answer N.
