__sinit initialises some common file descriptors as line buffered and
relies on the first users of such FDs to call __smakebuf_r. If
__smakebuf_r realises there's no space for a buffer (malloc returns
NULL), it makes them unbuffered. However, while setting the __SNBF
bit, it doesn't clear the __SLBF bit in the flags. Depending on the
order in which functions check buffering flags in the FD, sometime
they assume it's line buffered (e.g. __sfvwrite_r), trashing
application memory that's not really been allocated to them.

This patch solves the problem by clearing the unbuffered/line buffered
flag when setting the line buffered/unbuffered flag.
