glibc: remove bad patch snippet that eglibc forward ported
The s_sin.c patch undoes some code changes in glibc itself, these changes have nothing to
do with the option groups and I suspect crept in as part of the initial conversion. Undoing
this patch also fixes a test failure in test-double and test-idouble.
