Match names more precisely in update_lit_checks.py (#6190)

Previously the lit test update script interpreted module names as the names of
import items and export names as the names of export items, but it is more
precise to use the actual identifiers of the imported or exported items as the
names instead.

Update update_lit_checks.py to use a more correct regex to match names and to
correctly use the identifiers of import and export items as their names. In some
cases this can improve the readability of test output.
