Dmitry Chagin 3a66cf0372 Replace Linuxulator implementation of readdir(), getdents() and
getdents64() with wrapper over kern_getdirentries().

The patch was originally written by emaste@ and then adapted by trasz@
and me.

Note:
1. I divided linux_getdents() and linux_readdir() as in case when the
getdents() called with count = 1 (readdir() case) it can overwrite
user stack (by writing to user buffer pointer more than 1 byte).

2. Linux returns EINVAL in case when user supplied buffer is not enough
to contain fetched dirent.

3. Linux returns ENOTDIR in case when fd points to not a directory.
