Always use wordsize-64 version of s_rint.c.
This patch replaces s_rint.c in sysdeps/dbl-64 with the one in sysdeps/dbl-64/wordsize-64 and removes the latter one. The code is not changed except changes in code style. Also adjusted the include path in x86_64 file. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
