lua-posix: Update to 34.1.1

## Noteworthy changes in release 34.1.1 (2019-07-27) [stable]

### Bugs Fixed

  - `posix.compat` really does work without `std.normalize` in the
    `package.path` now.

## Noteworthy changes in release 34.1 (2019-07-20) [stable]

### Bugs Fixed

  - `luke` works with upgraded bootstrap luarocks version of `require`.

  - `posix.glob.glob` does not return a random errno on failure now, but
    new module constants `GLOB_ABORTED`, `GLOB_NOMATCH` or `GLOB_NOSPACE`.

  - `posix.deprecated.clock_getres` and `posix.deprecated.clock_gettime`
    work again.

### New Features

  - `posix.glob.glob` supports now module constants as a second argument:
    `GLOB_NOCHECK` and `GLOB_ERR`.

  - `posix.sys.socket` now supports IPV6 link-local addresses.

  - use `std.strict`, `std._debug` and `typecheck` modules when available,
    otherwise behave normally without those additional runtime checks.
