Enable parts of base_untrusted that are used by remoting client

1. base64, rand_util, threading, time and threads were previosly disabled in
base_untrusted. Remoting code depends on these parts of base, so they
need to be enabled.
2. Implemented NaCl version of rand_util.
3. Enabled glibc version of base_untrusted
