pty_driver: Freeze terminals when using regexp.

The pty driver has the ability to have regular expressions to check the
output after running some command.  However, if a user has a serial
terminal open, the command will fail because the serial console output
will go to the user's terminal instead of being caught by the pty_driver
functions.

This commit attempts to freeze any terminals that are in use when a
regexp is set.  The TerminalFreezer class has been moved here from it's
former home in chromite.

BUG= chromium:647109 
BRANCH=None
TEST=Open minicom for the EC console on kevin and cyan.  Verify that
`dut-control power_state:rec` succeeds without having to close minicom.
TEST=Verify servod starts successfully on a servo v3.
