tcl: prefer tcl's own tzdata

The little thread that was "one of the tcl test cases fails with system
tzdata" has unravelled upstream into a series of problems with the tz
code when the system tzdata is used:

https://core.tcl-lang.org/tcl/tktview/51aa53616067cb63900b17ca1d71f07b094ffa1a

Add a PACKAGECONFIG for the option, and default to using the tcl tzdata
until the issues are resolved upstream.
