Allow the run script environment to provide ERRATA_* variables
to the unit tests. These variables will augment/override variables
in any provided unit test environ (the file specified with $ENV)
or trigger the creation of a temporary environ file, which contains
them.
Now something like
ERRATA_abcd01234567=y ./run_tests.sh
may be run in order to inform all unit tests that they may execute
all subtests guarded by ERRATA_abcd01234567.
