Correct exit code from runulp.sh

The pipe prevented FAILs and PASSs being counted properly - the while
read loop has been rewritten without a pipe, as it was prior to the
changes here.

fenv checking is temporarily disabled in Neon sinh and sinhf, as they
do not get it right. This will be re-enabled once they have been
fixed.
