Add a prediff to fix .good mismatch

#19321 inadvertently enabled the testing of:

test/deprecated/RegexpModule.chpl
test/deprecated/regexp-rechan.chpl
test/deprecated/regexp_error.chpl

in the default configuration (and many others).

While they were not being tested, however, a difference in line numbers
in modules/standard/IO.chpl has crept in, so the test regexp-rechan.chpl
started to fail.

This PR adds a .prediff to eliminate sensitivity of this test
to such line numbers so now it passes.
