mercurial: 6.1.1 -> 6.1.2

Setting `HGMODULEPOLICY` for the tests is now required for the native
components to be properly detected when testing the already built binary
with `--with-hg`.

This release contains an important bug fix:
"Fix incorrect metadata causing dirstate-v2 data loss in edge case"
