Instead of using individual macros to turn off missing C library features, we use the using_if_exists attribute now. This patch removes the _LIBCPP_HAS_NO_FGETPOS_FSETPOS macro used to workaround missing fgetpos and fsetpos on older versions of Android -- using_if_exists should take care of those in the headers and we should add appropriate XFAILs to the tests instead of using TEST_HAS_NO_FGETPOS_FSETPOS.
