Don't run functionalities/tty under sudo / as root.

The terminal window will be opened under the ownership
of the real userid and it won't be able to open the
socket talking back to lldb -- the testsuite will hang
here.

The same thing probably should be done for lldb when run
on a remote system over ssh.  I added a line for that 
but commented it out for now because I haven't
tested it.
