Remove ldbl-opt w_scalbln.c [committed]

[Joseph Myers]

The ldbl-opt version of w_scalbln.c is not in fact needed; it handles
compat symbol versions for libc, but this file isn't built for libc,
only for libm.  This patch removes this file.

Tested with build-many-glibcs.py that installed stripped shared
libraries are unchanged by this patch.  Committed.
