jimtcl: update to 0.77, the current version, enable only specific modules

This is needed to fix build on aarch64 to get updated config.guess.

Because some newer JimTcl modules that get enabled are failing to
build on some of the platforms OpenOCD supports, enable only a
fixed set that shouldn't cause any issues.

We also disable running Jim Tcl tests on distcheck because they never
worked (before 85358e479e5bbf295a5aaf743f3c29a5e1a4fd1c Jim commit)
but didn't break Jenkins build; with newer version they're getting run
and fail due to limited permissions for filesystem and networking
operations.
