stream_smb: remove this

This required libsmbclient, which is a heavy dependency, and as a
library, has all kinds of problems. For one, the API requires completely
unacceptable global state (in particular, leaks auth state), and is not
thread-safe (meaning concurrent reads to multiple files block each
other).

There are better replacements: you can use the Linux kernel's builtin
CIFS support, fusesmb, or contribute supoport for libdsm.
