arch/alpha/fake_syscall.cc:
Fix a couple of bugs:
- error return codes weren't making it through due to inadvertent cast to unsigned
- sigreturn broken in not one but two ways
- make all file descriptors look like plain files (not ttys)
Added implementations of setuid, getgid, fcntl, and getdirentries from Dave Oehmke
