Fix ldbl-128ibm logl (1) sign of zero result (bug 19077).

The ldbl-128ibm implementation of logl produces a zero with the wrong
sign for logl (1) in FE_DOWNWARD mode.  This patch makes it explicitly
return 0.0L in that case, as in e.g. the ldbl-128 implementation.

Tested for powerpc.

[BZ #19077]
* sysdeps/ieee754/ldbl-128ibm/e_logl.c (__ieee754_logl): Return
0.0L for argument 1.0L.
