include: posix: unistd: Fix prototypes and dependency
For read/write/lseek, use size_t and off_t types, as mandated by POSIX: http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/unistd.h.html Also, prototypes of unistd.h functions should not depend on CONFIG_POSIX_FS, as (many) of them deal with generic I/O, not with files in filesystem per se.
