[PATCH] Add mask values for the default rune table.

[Dan Albert]

The `#else` case (waaaaaaay down at the bottom) already does this... my mistake.

For Android and newlib the problem is that the mask of the table isn't wide enough, so we run in to cases where we don't have `m & n == 0` for any `m` and `n` in the `ctype_base` masks. `_CTYPE_R`, for example, is `_CTYPE_P | _CTYPE_U | _CTYPE_L | _CTYPE_D | _CTYPE_B`, rather than just `1 << 1`.

For those implementations that have this issue, we can just fall through to the `#else` case and use the defaults.

jroelofs: you should submit that test case to keep us honest. I think we already have some tests that do that, but they're in tests that require more locale support (any) than some platforms (bionic, newlib) provide, so they don't get run.
