[PATCH 6/8] builtin/config: canonicalize "value_regex" with `--type=bool-or-int`

["Martin Ågren" <martin.agren@gmail.com>]

As an obvious follow-up to the previous commit, also canonicalize the
"value_regex" when the type is "bool-or-int".

Observe that in this case, falling back to handling the "value_regex" as
a normal regex is not just to cater to old scripts and habits. It is
necessary to handle the numerical inputs (or regexes matching some
specific numerical values!) that we must expect.

Future commits will expand on the code for `--type=bool`. Rather than
trying to shoehorn both these cases into a single chunk of code, let's
just duplicate some of the code from the previous commit.
