Remove uninitialized argument from openpty()

As per the docs:
    The openpty() function finds an available pseudoterminal and
    returns file descriptors for the master and slave in amaster and
    aslave. [...]  If termp is not NULL, the terminal parameters
    of the slave will be set to the values in termp. [...]

So openpty() would set the pty parameters to something undefined.
This undefinedness will be fixed by the later tcsetattr() call.
As a result, we don't need that parameter in the first place.
Additionally, fixes a -Wmaybe-uninitialized warning.
