internal/cuetest: consolidate testscript/cuetxtar helpers

Currently -update testing flags and the use of CUE_UPDATE to update the
golden files of testscript/cuetxtar scripts is littered throughout
various files/packages.

In this change we consolidate the use of -update flags to update golden
files into a single use of the CUE_UPDATE environment variable

We also defines a "long" build tag, along with an accompanying
testscript Condition function so that [long] can be used as a condition
in testscript scripts (used in a later CL)
