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.

Log message:
Simply and speed up buildlink3.mk files and processing.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

Log message:
