[git commit branch/0.9.33] linux: pread/pwrite: fix 64bit handling

[Mike Frysinger]

commit: http://git.uclibc.org/uClibc/commit/?id=525d31e51fca97051978aabd5a6295ffb8f82a17
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/0.9.33

This is a fix similar to 458076d59ef9849f79d27e21b6094b0b3a85fbb4.
But master has been rewritten heavily, so do a minor backport.
