persistent: Test failure on 32-bit arches with GHC 9.0.2

Over in Debian unstable, we're seeing a test failure on all 32-bit architectures (armel, armhf, i386, mipsel) when building persistent 2.13.3.5:

Failures:

  test/Database/Persist/THSpec.hs:240:26: 
  1) Database.Persist.THSpec.HasIdDef should have correct underlying sql type
       expected: SqlInt64
        but got: SqlInt32

  To rerun use: --match "/Database/Persist/THSpec/HasIdDef/should have correct underlying sql type/"

Test suite test: FAIL
Test suite logged to: dist-ghc/test/persistent-2.13.3.5-test.log

The tests are passing on 64-bit architectures (amd64, arm64, mips64el, ppc64el, s390x).

Full build logs for armel are available here: https://buildd.debian.org/status/fetch.php?pkg=haskell-persistent&arch=armel&ver=2.13.3.5-1&stamp=1659384152&raw=0

Start with test/Database/Persist/THSpec.hs:240 and rerun the named HasIdDef example using the provided --match selector. Compare the failing 32-bit result, SqlInt32, with the expected SqlInt64 and the passing 64-bit behavior. Done means the test suite passes on the affected 32-bit architectures without regressing the 64-bit cases.
