linux-user: fix getcwd syscall
The patch called "prefer glibc over direct syscalls" (commit 7118) has replaced the getcwd syscall with a call to the glibc. With this change, the syscall is returning -1 in error case and 0 otherwise. This is problematic as the sys_getcwd syscall should return the number of bytes written to the buffer including the '\0'.
