lang/tcl-expect: Upgrade from version 5.43 to 5.45

There doesn't appear to be a summary of changes between versions 5.43,
5.44 and 5.45.  Perusing the Changelog gives me the impression that
the updates are improvements and bug fixes against existing functionality.

Regardless, version 5.43 is incompatible with tcl8.5.  Expect had to
be updated after TCL was updated to version 8.5.
