Simplify hypotf infinity handling (bug 15918).

Bug 15918 points out that the handling of infinities in hypotf can be
simplified: it's enough to return the absolute value of the infinite
argument without first comparing it to the other argument and possibly
returning that other argument's absolute value.  This patch makes that
cleanup (which should not change how hypotf behaves on any input).

Tested for x86_64.

[BZ #15918]
* sysdeps/ieee754/flt-32/e_hypotf.c (__ieee754_hypotf): Simplify
handling of cases where one argument is an infinity.
