[Buildroot] [git commit branch/2023.05.x] package/libmdbx: bump version to 0.12.7 "Artek"

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=da9f314f9de6165d574c383372c882fd1a4fe7ce
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2023.05.x

This is bugfix release of stable libmdbx branch,
on the day of international children's camp «Artek».

It is reasonable to backport this patch to all applicable releases/branches of Buildroot.

The most significant fixes of v0.12.7:
 - added workaround for build issues with modern GCC using `-m32 -arch=i686 -Ofast`.
 - fixed the cause of the false-positive warning of modern GCC in the C++ API.
 - refined DB opening in "recovery" mode and switching to a given meta-page.
